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

Answer:

27 earned runs

Step-by-step explanation:

Given

Rate: 6 runs in 18 innings.

Required

Determine the number of runs in 81 innings

First, we need to calculate the rate.

$Rate = \frac{Runs}{Innings}$

$Rate = \frac{6}{18}$

$Rate = \frac{1}{3}$

Represent the number of runs in 81 innings as x.

The rate of x runs in 81 innings is;

$Rate = \frac{x}{81}$

Equate both rates

$\frac{1}{3} = \frac{x}{81}$

Make x the subject

$x = \frac{1}{3} * 81$

$x = \frac{81}{3}$

$x = 27$

Hence, he will give up 27 earned runs
