72 is what percent of 45?<br><br> __ = p/100<br><br> p= __
Marta_Voda [28]

Answer:

72 of 45 is 160%

Step-by-step explanation:

72 of 45 can be written as:

\frac{72}{45}

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

\frac{72}{45} *\frac{100}{100}

=(\frac{72*100}{45} )*\frac{1}{100} =\frac{160}{100}

Therefore, the answer is 160%

If you are using a calculator, simply enter 72÷45×100 which will give you 160 as the answer.
