What is 80% of 685?

Answer 1

In order to calculate 80% of 685, first let's convert the percentage into its fraction form or decimal form.

Converting it to its fraction form, we have:

`80\text{\%}=(80)/(100)`

Then, we need to multiply the fraction by the value 685:

`(80)/(100)\cdot685=(8)/(10)\cdot685=(4)/(5)\cdot685=(2740)/(5)=548`

Therefore the result is 548.

If we use the decimal form of the percentage, the result is the same:

`\begin{gathered} 80\text{\%}=0.8 \\ 0.8\cdot685=548 \end{gathered}`
