Question

I'm confused on number 13 and I need to know how to convert units.

Answer 1

In pounds...

2lb+1 3/4lb+(10oz)(lb/16oz)  change the mixed number to improper fraction

2+7/4+10/16   make all have a common denominator of 16

2(16/16)+(7/4)(4/4)+10/16

(32+28+10)/16

70/16

(64+6)/16

4+6/16

4+3/8

4 3/8 lbs
