A pitcher's earned run average is the number of earned runs allowed per game of 9 innings. A pitcher allows 20 earned runs in 50 innings. What is the pitcher's earned run average?

Answer:

Step-by-step explanation:

In baseball statistics, earned run average (ERA) is the average of earned runs given up by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.

The pitcher's earned run average is 3.6.

We are given that;

Number of innings=9

Now,

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

To find the pitcher's earned run average, we need to divide the number of earned runs by the number of innings, and then multiply by 9.

This is because we want to find the average number of earned runs per 9 innings, which is the standard length of a game.

Using this method, we get:

[tex]$\frac{20}{50} \times 9 = 3.6$[/tex]

Therefore, by unitary method answer will be 3.6.
