Sagot :

Applying a subtraction operation, it is found that his new ERA was of 3.17.

What is the relation between his two ERA's, in last year's and this year?

ERA is a baseball concept, but understanding of baseball is not relevant to this question.

One year, a professional baseball pitcher had a 3.91 ERA. The next year, it was 0.74 points lower, hence it was given by the subtraction of 3.91 and 0.74, that is:

ERA = 3.91 - 0.74 = 3.17.

His new ERA was of 3.17.
