Question #05db1

1 Answer

Oct 10, 2017

$80$ $80$ percent

Explanation:

I’m not sure how $a^{2} + b^{2} = c^{2}$ $a^2+b^2=c^2$ is related to this problem, but:

Percent means out of a hundred. So we have to change the fraction $\frac{4}{5}$ $4/5$ into a new fraction that has $100$ $100$ as the denominator.

To do that we have to multiply by a giant one:

$\frac{4 \cdot 20}{5 \cdot 20} = \frac{80}{100}$ $(4*20)/(5*20)=80/100$

Since this fraction is $80$ $80$ out of $100$ $100$ we can translate that into $80$ $80$ percent.
