Answer:

$\%Percent = 14.3\%$

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

$\%Percent = \frac{15}{105} * 100\%$

$\%Percent = \frac{15*100}{105}\%$

$\%Percent = \frac{1500}{105}\%$

$\%Percent = 14.3\%$ --- approximated
