y = 1 1/4 ÷ 7/8
y = 1.25 ÷ 0.875
y = 1.4286

8/9x = 2/9
x = (2/9) / (8/9)
x = 2/8
x = 1/4

5/9x = 1
x = 1 / (5/9)
x = 1.8

4/7x = 16
x = 16 / (4/7)
x = 28

x ÷ 8/16 = 32/45
x = 32/45 * (8/16)
x = 32/90
x = 16/45

7 1/5 ÷ x = 9/10
x = 7.2 / (36/5)
x = 7.2 * 5 / 36
x = 1

3 3/5 ÷ z = 1 4/5
z = 3.6 / 1.8
z = 2

x ÷ 5/6 = 12/13
x = 12/13 * (6/5)
x = 72/65
x = 1.1077

5 ÷ x = 1 1/14
x = 5 / 1.0714
x = 4.6667
