Question

What percent of 45 is 35?

Answer 1

`=77 7/9% ~~77.78%~~ 77.8%`

Explanation:

Write as a fraction first and then `xx 100%`

`35/45 xx 100%`

=`7/9 xx100%`

`=0.7777... xx 100%`

`=77 7/9% ~~77.78%~~ 77.8%`

As this is a recurring decimal it needs to be rounded off.
The number of decimal places will depend on the accuracy required.

The fraction form is exact and therefore more accurate.
