Question

If x is 125% of y, then y is what percent of x?

Answer 1

I assume that you mean y=125% of x

so y=1.25x

The question becomes What percentage of 8*1.25x is 5x

(5x) / (8*1.25x) *100 % = (5 / 10) *100%I assume that you mean y=125% of x

so y=1.25x

The question becomes What percentage of 8*1.25x is

Answer 2

Answer:

$\frac{125}{100} \times y = x$

$\frac{100}{125} \times x = y$

$\frac{4}{5} \times x = y$

Multiplying by 20 so that the denominator becomes 100 so as to obtain a percentage.

$\frac{4 \times 20}{5 \times 20} \times x = y$

$\frac{80}{100} \times x = y$

$y = 80\% \: of \: x$
