How to write 80 in words?

We generally used places to write any number in words. As expressed in the table given below:

As we can see in the table, there is 8 at the ten’s place and 0 at the one’s place.

Therefore we have to read it from right to left with its place values. So we have to read it as “Eight Ten”.

It looks odd, so a Two-digit number having its unit digit 0 and any other digit in its ten’s place is written as “Name of the digit in ten’s place followed by ty”.

Similarly, 80 is termed as “Eighty”

In expanded form, we can write the number 80 as

\begin{aligned}

&8 \times \text { Ten }+0 \times \text { One }\\

&=8 \times 10+0 \times 1 \\

&=80 \\

&=\text {Eighty }

\end{aligned}
