Question

4. 225 is 75% of what number?

Answer 1

Answer:

300

Step-by-step explanation:

$\frac{225}{x} = \frac{75}{100}$

Since 225 is 75% of a whole, write the proportion such that 225 corresponds to 75% and x, the number we're searching for, corresponds with 100%

Cross multiply to solve and divide by 75 to isolate x:

225 x 100 = 75x

22500 = 75x

300 = x
