Answer:
8
Step-by-step explanation:
1/10 bottle of paint covers 2/5 of box
2 bottles of paint will cover x of box
Using cross multiplication :
1/10 = 2 / 5
2 = x
(1 / 10)x = 2/5 * 2
x / 10 = 4 / 5
Cross multiply :
5x = 40
Divide both sides by 5
x = 40/5
x = 8
Hence, 2 bottles of paint will be used to paint 8 boxes
