Answer 1

Answer: 20

Explanation:

Given : The orchestra at millard middle school has 120 members.

Of these 17% are eighth grade students.

i.e. Percentage of eighth grade students in orchestra = 17%

Then, the number of eighth grade students in the orchestra. = (Percentage of eighth grade students in orchestra) x ( Total members in orchestra)

= 17% x 120

`=(17)/(100)*120` [We convert % into decimal by dividing it by 100]

`=20.4\approx20` [Round to the nearest integer.]

Hence, the estimated number of eighth grade students in the orchestra is 20.
