Answer 1

2a)
`1(7)/(16)`

2b)
`(5)/(48)`

Explanation:

The first thing we need to do is add all the fractions together so,

2a)
`2(1)/(2) +3(3)/(16)+(7)/(8)`

We need to find the LCM of the denominators in order to properly add the fractions together so the LCM is 16

`2(1)/(2) +3(3)/(16)+(7)/(8)` =
`2(8)/(16) +3(3)/(16) +(14)/(16) = 5(25)/(16) =6(9)/(16)`

Now we subtract this from 8 as asked in the question,

`8-6(9)/(16) =(8)/(1) -(105)/(16) =(128)/(16) -(105)/(16)=(23)/(16) =1(7)/(16)`

2b) We are asked to minus the fraction
`1(7)/(16)` from
`1(1)/(3)`

Find the common denominator which is 48

`1(7)/(16) -1(1)/(3) =1(21)/(48) -1(16)/(48) =(5)/(48)`

Answer 2

see below

Explanation:

2 1/2+ 3 3/16 + 7/8

Get a common denominator of 16

2 8/16 + 3 3/16 + 14/16

5 25/16

5 + 16/16 + 9/16

6 9/16

Subtract this from 8 ft

8 - 6 9/16

Borrow 1 from 8 in the form of 16/16

7 16/16 - 6 9/16

1 7/16

b 1 7/16 - 1 1/3

The common denominator is 48

1 21/48 - 1 16/48

5/48
