5x2 1/3=
6x2 3/4=
3/8x 4/7=
2 3/5x 10/13=
3/10x 3 1/8=

Answer 1

5·2 i 1/3=5·7/3=35/3=11 i 2/3
6·2 i 3/4=6·11/4=33/2=16 i 1/2
3/8·4/7=3/14
2 i 3/5·10/13=13/5·10/13=10/5=2
3/10·3 i 1/8=3/10·25/8=15/16

Answer 2

5 * 2 i 1/3 = 5 * 7/3 = 35/3 = 11 i 2/3

6 * 2 i 3/4 = 6 * 11/4 = 66/4 = 16 i 2/4 = 16 i 1/2

3/8 * 4/7 = 3/14

2 i 3/5 * 10/13 =13/5 * 10/13 = 2

3/10 * 3 i 1/8 = 3/10 * 25/8 = 15/16
