Question

A baseball player gives up 6 earned runs in 18 innings . If he continues at this rate how many earned runs will he give up in 81 innings?​

Answer 1

27 earned runs

Explanation:

Given

Rate: 6 runs in 18 innings.

Required

Determine the number of runs in 81 innings

First, we need to calculate the rate.

`Rate = (Runs)/(Innings)`

`Rate = (6)/(18)`

`Rate = (1)/(3)`

Represent the number of runs in 81 innings as x.

The rate of x runs in 81 innings is;

`Rate = (x)/(81)`

Equate both rates

`(1)/(3) = (x)/(81)`

Make x the subject

`x = (1)/(3) * 81`

`x = (81)/(3)`

`x = 27`

Hence, he will give up 27 earned runs
