Question

A child grew 3 1/4 inches one year and 4 3/4 inches the next year. How many inches did the child grow over the two years?

Answer 1

8 inches.

Explanation:

3 1/4 + 4 3/4

= 3 + 4 + 1/4 + 3/4

= 7 + 4/4

= 7 + 1

= 8 inches.

Answer 2

The child grew 8 inches

Explanation:

Step 1: Convert to improper fractions

`3(1)/(4)`

`(1+(3*4))/(4)`

`(1+12)/(4)`

`(13)/(4)`

`4(3)/(4)`

`(3+(4*4))/(4)`

`(3+16)/(4)`

`(19)/(4)`

Step 2: Combine the fractions

`(13)/(4)+(19)/(4)`

`(13+19)/(4)`

`(32)/(4)`

`8`

Answer: The child grew 8 inches
