Question

Match the addition and subtraction problems to their solutions:

__5/7-3/7 A. 1/24

__1/6+3/6 B. 2/7

__1/2+1/4 C. 2/3

__1/5+1/2 D. 7/10

__1/6-1/8 E. 3/4

Answer 1

The matching is defined as 1-B, 2-C, 3-E, 4-D, 5-A.

Explanation:

The given expression are

1.
`(5)/(7)-(3)/(7)=(5-3)/(7)=(2)/(7)`

Therefore the answer of this expression is option B.

2.
`(1)/(6)+(3)/(6)=(1+3)/(6)=(4)/(6)=(2)/(3)`

Therefore the answer of this expression is option C.

3.
`(1)/(2)+(1)/(4)=(2(1)+1)/(4)=(3)/(4)`

Therefore the answer of this expression is option E.

4.
`(1)/(5)+(1)/(2)=(2(1)+5(1))/(10)=(7)/(10)`

Therefore the answer of this expression is option D.

5.
`(1)/(6)-(1)/(8)=(8(1)-6(1))/(48)=(2)/(48)=(1)/(24)`

Therefore the answer of this expression is option A.

Thus the matching is defined as 1-B, 2-C, 3-E, 4-D, 5-A.

Answer 2

5/7 - 3/7 = 2/7 B

1/6 + 3/6 = 4/6 = 2/3 C

1/2 + 1/4 = 2/4+ 1/4 = 3/4 E

1/5 + 1/2 = 2/10 +5/10 = 7/10 D

1/6 - 1/8 = 4/24 - 3/24 = 1/24 A
