Of the 350 children attending an elementary school, 24% of them are enrolled in the instrumental music program. Estimate the number of children taking instrumental music.
Answer = (1)
Correct Answer
Explanation
We will use the rule from this section for finding 25% of a number. 24% is approximately 25%, and there is a quick way to find 25% of a number.
Solution
24% of the 350 children in the school are taking instrumental music. To estimate 24% of 350, we will find 25% of 360. We use 360 as an approximation because it is close to 350 and it is divisible by 4.
24% of 350 ≈ 90 (Because 25% of 360 = \(\frac{360}{4}\) = 90)
There are approximately 90 children in the school taking instrumental music.
