Question

What percent of 72 is 9? 1/8% 1 1/4% 12 1/2% 125%

Answer 1

`12\frac 12\%`

Step by step explanation:

`\text{Let it be}~ x\%,\\\\~~~~~72 \cdot x \% = 9\\\\\\\implies 72\cdot (x)/(100) = 9\\\\\\\implies x = (9 * 100)/(72)\\\\\\\implies x = (100)/(8)\\\\\\\implies x = \frac{25}2\\\\\\\implies x = 12 \frac 12\\\\\\\text{Hence 9 is}~ 12\frac 12\% ~ \text{of}~ 72`
