¾k = 12/20
3/4 x 4/3 = 12/20 x 4/3 k = Reciprocal of 3/4 is Reciprocal of 2/6 is Reciprocal of 7/8 is 2/6 s = 6/24
2/6s ×6/2 = 6/24 x
s = 7/8 k = 28/40
7/8 k × 8/7 = 28/40 x 8/7
k = -5/10 = -2/3n
-5/10 x -3/2 = -2/3n x -3/2
n = 1/2m = 2/4
1/2m x 2/1 = 2/4 x 2/1
m= -6k = 24/4
-6k × -1/6 = 24/4 × -1/6
k = -5c = 75/25
-5c × -1/5 = 75/25 × -1/5
