Answer 1

4/3 + 3/3 = 7/3

5/2 x 4 = 10

2 - 7/8 = 16/8 - 7/8 = 9/8

5 x 7/5 = 7

5/6 x 7/2= 35/12

Answer 2

4/3 + 3/3 = 7/3

5/2 x 4 = 10

2 - 7/8 = 16/8 - 7/8 = 9/8

5 x 7/5 = 7

5/6 x 7/2= 35/12

Answer 3

4/3 + 3 = 13/3

5/2 x 4 = 10

2 - 7/8 = 9/8

9/4 - 2 = 1/4

5:5/7 = 7

5/6 : 2/7 = 35/12

Answer 4

4/3 + 3 = 13/3

5/2 x 4 = 10

2 - 7/8 = 9/8

9/4 - 2 = 1/4

5 : 5/7 = 1/7

5/6 : 2/7 = 35/12

Answer 5

\(\dfrac{4}{3}+3=\dfrac{4}{3}+\dfrac{3}{1}=\dfrac{4}{3}+\dfrac{9}{3}=\dfrac{13}{3}\)

\(\dfrac{5}{2}x4=\dfrac{5}{2}x\dfrac{4}{1}=\dfrac{10}{1}=10\)

\(2-\dfrac{7}{8}=\dfrac{2}{1}-\dfrac{7}{8}=\dfrac{16}{8}-\dfrac{7}{8}=\dfrac{9}{8}\)

\(\dfrac{9}{4}-2=\dfrac{9}{4}-\dfrac{2}{1}=\dfrac{9}{4}-\dfrac{8}{4}=\dfrac{1}{4}\)

Answer 6

4/3 + 3/3 = 7/3

5/2 x 4 = 10

2 - 7/8 = 16/8 - 7/8 = 9/8

5 x 7/5 = 7

5/6 x 7/2= 35/12
