Question

Match the addition and subtraction problems to their solutions:

Answer 1

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

Answer 2

Answer:

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

Step-by-step explanation:

The given expression are

1. $\frac{5}{7}-\frac{3}{7}=\frac{5-3}{7}=\frac{2}{7}$

Therefore the answer of this expression is option B.

2. $\frac{1}{6}+\frac{3}{6}=\frac{1+3}{6}=\frac{4}{6}=\frac{2}{3}$

Therefore the answer of this expression is option C.

3. $\frac{1}{2}+\frac{1}{4}=\frac{2(1)+1}{4}=\frac{3}{4}$

Therefore the answer of this expression is option E.

4. $\frac{1}{5}+\frac{1}{2}=\frac{2(1)+5(1)}{10}=\frac{7}{10}$

Therefore the answer of this expression is option D.

5. $\frac{1}{6}-\frac{1}{8}=\frac{8(1)-6(1)}{48}=\frac{2}{48}=\frac{1}{24}$

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.
