Solution:

(a) $\frac{3}{10}+3 \frac{4}{100}$
$=\frac{30}{100}+3+\frac{4}{100}$
$=3+\left(\frac{30}{100}+\frac{4}{100}\right)$
$=3+\frac{34}{100}=3 \frac{34}{100}$

(b) $9 \frac{5}{10} \frac{7}{100}+2 \frac{1}{10} \frac{3}{100}$
$=(9+2)+\left(\frac{5}{10}+\frac{1}{10}\right)+\left(\frac{7}{100}+\frac{3}{100}\right)$
$=11+\left(\frac{5+1}{10}\right)+\left(\frac{7+3}{100}\right)$
$=11+\frac{6}{10}+\frac{10}{100}$
$=11+\frac{6}{10}+\frac{1}{10}=11+\frac{7}{10}=11 \frac{7}{10}$

(c) $15 \frac{6}{10} \frac{4}{100}+14 \frac{3}{10} \frac{6}{100}$
$=(15+14)+\left(\frac{6}{10}+\frac{3}{10}\right)+\left(\frac{4}{100}+\frac{6}{100}\right)$
$=29+\left(\frac{6+3}{10}\right)+\left(\frac{4+6}{100}\right)$
$=29+\frac{9}{10}+\frac{10}{100}$
$=29+\frac{9}{10}+\frac{1}{10}$
$=29+\frac{10}{10}=29+1=30$

(d) $7 \frac{7}{100}-4 \frac{4}{100}$
$=(7-4)+\left(\frac{7}{100}-\frac{4}{100}\right)$
$=3+\frac{3}{100}=3 \frac{3}{100}$

(e) $8 \frac{6}{100}-5 \frac{3}{100}$
$=(8-5)+\left(\frac{6}{100}-\frac{3}{100}\right)$
$=3+\frac{3}{100}=3 \frac{3}{100}$

(f) $12 \frac{6}{10} \frac{2}{100}-\frac{9}{10} \frac{9}{100}$
$=12 \frac{62}{100}-\frac{99}{100}$

$=11+\frac{100}{100}+\frac{62}{100}-\left(\frac{99}{100}\right)$
$=11+\frac{162}{100}-\left(\frac{99}{100}\right)$
$=11+\left(\frac{162}{100}-\frac{99}{100}\right)$

Question 1: Convert the following fractions into decimals:

(a) $\frac{5}{100}$ (b) $\frac{16}{1000}$ (c) $\frac{12}{10}$ (d) $\frac{254}{1000}$

Solution:

(b) $\frac{16}{1000}$ = 0.016

(c) $\frac{12}{10}$ = 1.2

(d) $\frac{254}{1000}$ = 0.254

Question 2: Convert the following decimals into a sum of tenths, hundredths and thousandths:

(a) 0.34 (b) 1.02 (c) 0.8 (d) 0.362

Solution:

(a) $0.34=\left(3 \times \frac{1}{10}\right)+\left(4 \times \frac{1}{100}\right)=\frac{3}{10}+\frac{4}{100}$

(b) $1.02=(1 \times 1)+\left(2 \times \frac{1}{100}\right)=1+\frac{2}{100}$

(c) $0.8=\left(8 \times \frac{1}{10}\right)=\frac{8}{10}$

(d) $0.362=\left(3 \times \frac{1}{10}\right)+\left(6 \times \frac{1}{100}\right)+\left(2 \times \frac{1}{1000}\right)=\frac{3}{10}+\frac{6}{100}+\frac{2}{1000}$

Question 3: What decimal number does each letter represent in the number line below?

Solution:

Total divisions between 6.4 and 6.6 = 8

Each division = $\frac{6.6-6.4}{8}$ = $\frac{0.2}{8}$ = $\frac{2}{80}$ = 0.025

Therefore,

$a=6.4+(2 \times 0.025)=6.4+0.050=6.425$

$c=6.4+(5 \times 0.025)=6.4+0.125=6.525$

$b=6.4+(6 \times 0.025)=6.4+0.150=6.550$

Question 4: Arrange the following quantities in descending order:

(a) 11.01, 1.011, 1.101, 11.10, 1.01

(b) 2.567, 2.675, 2.768, 2.499, 2.698

(c) 4.678 g, 4.595 g, 4.600 g, 4.656 g, 4.666 g

(d) 33.13 m, 33.31 m, 33.133 m, 33.331 m, 33.313 m

Solution:

(a) $11.10>11.01>1.101>11.011>1.01$

(b) $2.768>2.698>2.675>2.567>2.499$

(c) $4.678 \mathrm{~g}>4.666 \mathrm{~g}>4.656 \mathrm{~g}>4.600 \mathrm{~g}>4.595 \mathrm{~g}$

(d) $33.331 \mathrm{~m}>33.313 \mathrm{~m}>33.31 \mathrm{~m}>33.133 \mathrm{~m}>33.13 \mathrm{~m}$

Question 5: Using the digits 1, 4, 0, 8, and 6, make:

(a) The decimal number closest to 30

(b) The smallest possible decimal number between 100 and 1000.

Solution:

(a) Possible numbers: 14.860,40.168

30 – 14.860 = 15.14

40.168 – 30 = 10.168

Therefore, 40.168 is the closest number to 30.

(b) The smallest possible decimal number between 100 and 1000 is 104.68.

Question 6: Will a decimal number with more digits be greater than a decimal number with fewer digits?

Solution:

Maybe, but not always. A number with more decimal digits can be smaller.

For Example:

0.12 has 2 decimal digits.

0.111 has 3 decimal digits.

But, 0.12 > 0.111

Question 7: Mahi purchases 0.25 kg of beans, 0.3 kg of carrots, 0.5 kg of potatoes, 0.2 kg of capsicums, and 0.05 kg of ginger. Calculate the total weight of the items she bought.

Solution:

Total weight = (0.25 + 0.3 + 0.5 + 0.2 + 0.05) kg = 1.3 kg

Question 8: Pinto supplies 3.79 L, 4.2 L, and 4.25 L of milk to a milk dairy in the first three days. In 6 days, he supplies 25 litres of milk. Find the total quantity of milk supplied to the dairy in the last three days.

Solution:

Milk supplied in first 3 days = (3.79 + 4.2 + 4.25) L = 12.24 L

Milk supplied in 6 days = 25 L

Therefore, Milk supplied in the last three days = (25 – 12.24) L = 12.76 L

Question 9: Tinku weighed 35.75 kg in January and 34.50 kg in February. Has he gained or lost weight? How much is the change?

Solution:

Since 35.75 > 34.50,

Therefore, he has lost weight.

Change in weight = (35.75 – 34.50) kg = 1.25 kg

So, Tinku has lost 1.25 kg.

Question 10: Extend the pattern: 5.5, 6.4, 6.39, 7.29, 7.28, 6.18, 6.17, ____, _____

Solution:

Pattern alternates: +0.9, –0.01, +0.9, –0.01, –1.1, –0.01,

Therefore, the next two terms are: 5.07 (–1.1), 5.06 (–0.01).

Question 11: How many millimetres make 1 kilometre?

Solution:

1 km = 1000 m = (1000 × 1000) mm = 10,00,000 mm.

Question 12: Indian Railways offers optional travel insurance for passengers who book e-tickets. It costs 45 paise per passenger. If 1 lakh people opt for insurance in a day, what is the total insurance fee paid?

Solution:

45 paise = Rs 0.45

1 lakh = 1,00,000

The total insurance fee paid = (1,00,000 × 0.45) = Rs. 45,000

Question 13: Which is greater?

(a) $\frac{10}{1000}$ or $\frac{1}{10}$?

(b) One-hundredth or 90 thousandths?

(c) One-thousandth or 90 hundredths?

Solution:

(a) $\frac{10}{1000}=\frac{1}{100}=0.01$

$\frac{1}{10}=0.1$

Since $0.01<0.1$

Therefore, $\frac{10}{1000}<\frac{1}{10}$

(b) One-hundredth $=\frac{1}{100}=0.01$

90 thousandths $=\frac{90}{1000}=\frac{9}{100}=0.09$

Since $0.01<0.09$

$\therefore$ One-hundredth $<$ 90 thousandths.

(c) One thousandth $=\frac{1}{1000}=0.001$

90 hundredths $=\frac{90}{100}=\frac{9}{10}=0.9$

Since $0.001<0.9$

$\therefore$ One-thousandth < 90 hundredths.

Question 14: Write the decimal forms of the quantities mentioned (an example is given):

(a) 87 ones, 5 tenths and 60 hundredths = 88.10

(b) 12 tens and 12 tenths

(c) 10 tens, 10 ones, 10 tenths, and 10 hundredths

(d) 25 tens, 25 ones, 25 tenths, and 25 hundredths

Solution:

(a) 87 ones, 5 tenths and 60 hundredths

$=(87 \times 1)+\left(5 \times \frac{1}{10}\right)+\left(60 \times \frac{1}{100}\right)$

$=87+\frac{5}{10}+\frac{6}{10}$

$=87+0.5+0.6=88.10$

(b) 12 tens and 12 tenths
$=(12 \times 10)+\left(12 \times \frac{1}{10}\right)$
$=120+\frac{12}{10}$
$=120+1.2=121.2$

(c) 10 tens, 10 ones, 10 tenths, and 10 hundredths
$\begin{aligned}
& =(10 \times 10)+(10 \times 1)+\left(10 \times \frac{1}{10}\right)+\left(10 \times \frac{1}{100}\right) \\
& =100+10+1+\frac{1}{10} \\
& =100+10+1+0.1 \\
& =111.1
\end{aligned}$

(d) 25 tens, 25 ones, 25 tenths, and 25 hundredths
$\begin{aligned}
& =(25 \times 10)+(25 \times 1)+\left(25 \times \frac{1}{10}\right)+\left(25 \times \frac{1}{100}\right) \\
& =250+25+\frac{25}{10}+\frac{25}{100} \\
& =250+25+2.5+0.25 \\
& =277.75
\end{aligned}$

(a) $\frac{1}{2}$ (b) $\frac{3}{2}$ (c) $\frac{1}{4}$ (d) $\frac{3}{4}$ (e) $\frac{1}{5}$ (f) $\frac{4}{5}$

Solution:

(a) $\frac{1}{2}=\frac{1}{2} \times \frac{10}{10}=\frac{5}{10}=0.5$

(b) $\frac{3}{2} =\frac{3}{2} \times \frac{10}{10}=\frac{15}{10}=1.5$

(c) $\frac{1}{4} =\frac{1}{4} \times \frac{100}{100}=\frac{25}{100}=0.25$

(d) $\frac{3}{4} =\frac{3}{4} \times \frac{100}{100}=\frac{75}{100}=0.75$

(e) $\frac{1}{5} =\frac{1}{5} \times \frac{10}{10}=\frac{2}{10}=0.2$

(f) $\frac{4}{5} =\frac{4}{5} \times \frac{10}{10}=\frac{8}{10}=0.8$
