Answer 1

a

2/5 = 2/5 * 2/2 = 4/10:>>>

2/5 * 3/3= 6/15 >>>

2/5 * 4/4 = 8/20>>>>

2/5 * 5/5 = 10/25 >>>>

2/5 * 6/6 = 12/30 >>>>

b

4/5 * 2/2= 8/10 >>>

4/5 *3/3 = 12/15 >>>

4/5 *4/4 =16/20 >>>>

4/5 * 5/5 = 20/25 >>>

4/5 *6/6 = 24/30 >>>>

c

28/70 : 2/2 = 14/35 >>>

28/70 : 7/7 = 4/10 >>>

28/70 : 14/14 = 2/5>>>

28/70 * 2/2 = 56/140 >>>>

28/70 * 3/3 =84/210 >>>>

d

3/2 * 2/2 = 6/4 >>>>

3/2 * 3/3= 9/6 >>>>

3/2 * 4/4 = 12/8 >>>

3/2 * 5/5 = 15/10 >>>

3/2 * 6/6 = 18/12 >>>

e

60/32 : 2/2 = 30/16 >>>>

60/32 : 4/4= 15/8 >>>>

60/32 * 2/2= 120/64 >>>>

60/32 * 3/3 = 180/96 >>>>>

60/32 * 4/4 = 240/128 >>>>>
