Question

Number 4; Find the actual difference. ___________ There are ______ pounds of chicken remaining.

Answer 1

Total amount of chicken:

`3(1)/(2)pounds`

Amount used for fajitas:

`1(1)/(3)`

To calculate how many pounds of chicken are left we have to subtract the amount used for fajitas to the total amount:

`3(1)/(2)-1(1)/(3)`

Turn mixed numbers into improper fractions:

`((3*2)+1)/(2)-((3*1)+1)/(3)`
`(7)/(2)-(4)/(3)`

multiply the first fraction by (3/3) and the second fraction by (2/2)

`((7)/(2)*(3)/(3))-((4)/(3)*(2)/(2))`
`(21)/(6)-(8)/(6)`

Subtract:

`(13)/(6)`

To express it as a mixed number:

`2(1)/(6)`
