Answer 1

1) 7x2=14+7x1/2=17i1/2

 

Answer 2

1)

7 * 2 i 1/2 = 7 * 5/2 = 35/2 = 18 i 1/2

2)

5 i 1/3 * 2 = 16/3 * 2 = 32/3 = 10 i 2/3

3)

8 * 3 2/5 = 8 * 17/5 = 136/5 = 27 i 1/5

4)

8 i 1/3 * 4 = 25/3 * 4 = 100/3 = 33 i 1/3

5)

1 i 3/5 * 6 = 8/5 * 6 = 48/5 = 9 i 3/5

6)

10*2 i 1/3 = 10 * 5/3 = 50/3 = 16 i 48

7)

6 i 3/7 * 2 = 45/7 * 2 = 90/7 = 12 i 6/7

8)

4 * 3 i 2/9 = 4 * 29/9 = 116/9 = 12 i 8/9
