Answer 1

You just subtract the amount he grew from his actual height. 56 7/8 minus 4 1/4 would be 52 5/8 inches. 

Answer 2

`52(5)/(8)` inches

Explanation:

We are given that brad grew
`4(1)/(4)` inches this year and now height of brad is
`56(7)/(8)` inches

We have to write an equation for finding of height of Brad and find the height of brad at the start of this year.

Let x be the height of Brad at the start of this year

According to question

`x+4(1)/(4)=56(7)/(8)`

`x+(17)/(4)=56 (7)/(8)`

`x=(455)/(8)-(17)/(4)`

`x=(455-34)/(8)`

`x=(421)/(8)`

`x=52(5)/(8)`

Hence, the height of brad at this year =
`52(5)/(8)` inches
