Question

75% of 64 is 120% of:
A
38

Answer 1

Answer:

48

Step-by-step explanation:

We must first find what is 75% of 64 (x), in order to find what this number is 120% of (y).

To find percentages, we can use the formula$\frac{is}{of}=\frac{p percent}{100}$, and we cross multiply and divide to find either the is value, of value, or the percent.

Thus, we have$\frac{x}{64}=\frac{75}{100}\\ \\ 100x=(64*75)\\\\\frac{(100x=(64*75))}{100} \\\\x=48$

Now we want to find what 48 is 120% of:

$\frac{48}{y}=\frac{120}{100} \\\\ 120y=(48*100)$

$\frac{(120y=(48*100)}{120} \\\\y=40$
