Four ninths plus one ninth

5/9

Step-by-step explanation:

4/9 + 1/9

To add fractions, you need a common denominator. You already have a common denominator of 9, so just add the numerators.

4/9 + 1/9 = 5/9

Since there is no common factor of 5 and 9 other than 1, the fraction is already reduced.

5/9

the range is 19

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
