Question

Carlos has 7 1/2 acres of farmland. He uses 1/3 of the acres to graze animals and 1/5 of the acres to grow vegetables . How many acres does Carlos use for grazing animals or for growing vegetables.??

Answer 1

6 29/30 because 1/3=10/30 and 1/5= 6/30. 6/30+10/30=16/30 an 7 1/2= 7 15/30. 7/15/30-16/30+ 6/29

Answer 2

Answer: 4 acres

Explanation:

Given: The number of acres farmland Carlos has =
`7(1)/(2)\ acres`

The land he uses to graze animals =
`(1)/(3)*7(1)/(2)`

`=(1)/(3)*(15)/(2)\\\\=(5)/(2)\ acres`

The land he uses to grow vegetables =
`(1)/(5)*7(1)/(2)`

`=(1)/(5)*(15)/(2)\\\\=(3)/(2)\ acres`

The land he uses to graze animals or for growing vegetables=
`(5)/(5)+(3)/(2)=(8)/(2)=4\ acres`
