a. 89 1/10 pounds
b. 87 7/10 pounds
c. 84 13/20 pounds
d. 89 19/20 pounds

Answer 1

A

Explanation:

1st package weighs
`12(1)/(2)` pounds;

2nd package weighs
`35(1)/(4)` pounds;

3rd package weighs
`41(7)/(20)` pounds;

First, add whole numbers:

`12+35+41=88`

Now add fractions:

`(1)/(2)+(1)/(4)+(7)/(20)=(10)/(20)+(5)/(20)+(7)/(20)=(10+5+7)/(20)=(22)/(20)=(11)/(10)=1(1)/(10)`

So, the total weight is

`88+1(1)/(10)=89(1)/(10)\ pounds`
