Question

Dan's parents keep a chart on the wall where they mark how much Dan grows each year. When Dan was 15, he grew 3/10 of an inch and when he was 16, he grew 8/10 of an inch. In total, how much did Dan grow in during those two years?

Write your answer as a fraction or as a whole or mixed number.

Answer 1

`1(1)/(10)`

Explanation:

Given

Dan grew
`(3)/(10)` of an inch, when he was 15.

Dan grew
`(8)/(10)` of an inch, when he was 16.

Dan grow during these two years by adding growth of year 15 and 16

Such as

`growth=(3)/(10)+(8)/(10)`

`growth=(3+8)/(10) \\growth=11/10`

And also we write the answer in whole or mixed number such as

=
`1(1)/(10)`
