Answer:
62.50%
Step-by-step explanation:
Here we are required to find that what 45 is percentage of 72.
Let us supposed that x% of 72 gives us 45.
Hence
x% of 72 = 45
\(\frac{x}{100}\) 72 =45
\(\frac{72x}{100}\) =45
Multiplying boht sides by 100 we get
72x = 45100
72x = 4500
dividing both sides by 72
\(\frac{72x}{72}=\frac{4500}{72}\)
x=62.50
Hence we get
62.50 % of 72 is 45
or
45 is 62.50% of 72
