If 12 children represents 12.5% of the people attending a concert, how many people are attending the concert

NeTakaya

96 people are attending the concert.

Step-by-step explanation:

Given,

Number of children at concert = 12

This represents 12.5% of the people attending concert.

Let,

p be the total people attending concert.

12.5% of p = 12

$\frac{12.5}{100}*p=12\\0.125p=12$

Dividing both sides by 0.125

$\frac{0.125p}{0.125}=\frac{12}{0.125}\\p=96$

96 people are attending the concert.
