c) 5/9:25/6
d) 8/21: 6/7
e) 2 7/9 : 1 2/3
f)1 2/3 : 2 7/9
g) 4: 6 2/5
h) 6 2/9 :7

Answer 1

c)
5/9:25/6 = 5/9 * 6/25 = 1/3 * 2/5 = 2/5
d)
8/21: 6/7 = 8/21 * 7/6 = 4/3 * 1/3 = 4/9
e)
2 7/9 : 1 2/3 = 25/9 : 5/3 = 25/9 * 3/5 = 5/3 = 1 2/3
f)1
2/3 : 2 7/9 = 2/3 : 25/9 = 2/3 * 9/25 = 2 * 3/25 = 6/25
g)
4: 6 2/5 = 4 : 32/5 = 4 * 5/32 = 5/8
h)
6 2/9 :7 = 56/9 * 1/7 = 8/9

Answer 2

C) 5/9:25/6=5/9*6/25=2/15
d) 8/21:6/7=8/21*7/6=4/9
e) 2 7/9:1 2/3 = 25/9:5/3 = 25/9*3/5=5/3
f) 1 2/3:2 7/9 = 5/3:25/9=5/3*9/25=3/5
g) 4:6 2/5 = 4:32/5=4/1*5/32=5/8
h) 6 2/9:7 = 56/9:7 = 56/9*1/7 = 8/9
