Jasper's parents keep a chart on the wall where they mark how much Jasper grows each year. When Jasper was 15, he grew 1/10 of an inch and when he was 16, he grew 3/10 of an inch. In total, how much did Jasper grow in during those two years? Write your answer as a fraction or as a whole or mixed number.

In order to find the total inches Jasper grew during the two years, we have to add up the total inches he grew when he was 15 and the total inches he grew when he was 16. Therefore, we have to add 1/10 and 3/10 together.

1/10 + 3/10 = 4/10, or 2/5.

Therefore, Jasper grew a total of 2/5 inches in those two years.
