a)
m : 5 : 3×2 = 30
m : 5 : 3 = 30 : 2
m : 5 : 3 = 15
m : 5 = 15×3
m : 5 = 45
m = 45 × 5
m = 225
b)
m : 2 × 3 : 4 = 48
m : 2 × 3 = 48×4
m : 2 × 3 = 192
m : 2 = 192 : 3
m : 2 = 64
m = 64 × 2
m = 128
c)
m × 4 : 10 × 3 = 24
m × 4 : 10 = 24 : 3
m × 4 : 10 = 8
m × 4 = 8 × 10
m × 4 = 80
m = 80 : 4
m = 20
