9 3/4 lb= oz...How many ounces once converted and simplified

Question

We are doing conversion and the fractions are confusing me when we convert

Answer 1

16(9 3/4)

16(9 + 3/4)

(16)(9) + (16)(3/4)

144 + 12

156

Answer 2

9 3/4 lb = 39/4 lb

16 oz/1b

 

16 oz/lb * 39/4  lb = 156 oz

 

The trick with unit conversions is to make the units work out: oz/lb * lb = oz
