Question

54 is 120% of what number? Explain please!

Answer 1

$\displaystyle \text{54 is 120\% of what number} \\ \text{is will be = } \\ \text{of will be } \cdot \\ \text{what number will be z} \\ ---------- \\ 54=120\% \cdot z \\ \\ 54= \frac{120}{100}\cdot z \\ \\\\ z \cdot \frac{120}{100}=54 \\ \\ \\ z=54 : \frac{120}{100} \\ \\ \\ z=54 \cdot \frac{100}{120} \\ \\ \\ z= \frac{5400}{120} =45$

Answer 2

54 is 120% of the number 64.8 .

If you put 120% in decimal form it's 1.2 if you do 1.2 and multiply it by 54 you get 64.8.

And to check it if you take 64.8 and divide that by 54 you get 1.2 and which is again equivalent to 120%.

I hope this helps a bit.
