Kipish [7]

Answer:    70

plz give brainliest

Step-by-step explanation:

Solution:

Since

96 : 160 = 42 : X

Then we know

160/96 = X/42

Multiplying both sides by 42 cancels on the right

42 × (160/96) = (X/42) × 42

42 × (160/96) = X

Then solving for X

X = 42 × (160/96)

X = 70

Therefore

96 : 160 = 42 : 70
