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
[tex]\frac{x}{100}[/tex] * 72 =45
[tex]\frac{72x}{100}[/tex] =45
Multiplying boht sides by 100 we get
72x = 45*100
72x = 4500
dividing both sides by 72
[tex]\frac{72x}{72}=\frac{4500}{72}[/tex]
x=62.50
Hence we get
62.50 % of 72 is 45
or
45 is 62.50% of 72
