Question

I bought 3 1/4 lbs of apples, 2 2/3 lbs of oranges, 5 3/4 lbs of peaches and 3 1/3 lbs of bananas. How many pounds of fruit did I buy?

Answer 1

`=3(1)/(4) + 2(2)/(3)+5(3)/(4)\\\\`

=
`(13)/(4) + (8)/(3) + (23)/(4)`

`=((13*3)+(8*4)+(23*3))/(12) \\\\=(39 + 32 + 69)/(12) \\\\=(140)/(12)\\\\=(35)/(3)\\\\ = 11(2)/(3)lbs`
