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

Answer:

$=3\frac{1}{4} + 2\frac{2}{3}+5\frac{3}{4}$

=$\frac{13}{4} + \frac{8}{3} + \frac{23}{4}$

$=\frac{(13*3)+(8*4)+(23*3)}{12} \\\\=\frac{39 + 32 + 69}{12} \\\\=\frac{140}{12}\\\\=\frac{35}{3}\\\\ = 11\frac{2}{3}lbs$
