a cargo truck can carry 180 cavans of rice or 220 boxes of milk. given that 60 cavans of rice already loaded to the cargo truck, how many boxes of milk can still be loaded on the truck?

Sagot :

It could still carry 147 boxes of milk. Knowing that 60 is 1/3 of 180 cavans of rice, the truck will be filled with an additional 2/3 of either 180 cavans of rice (which is 120) or 220 boxes of milk(which is 146.67 or 147). Since it demands milk, we take the 2/3 of 220 boxes of milk, which is 146.67 or 147. The solution is a proportion.. "(180/120) = (220/x)" where x is 147. Hope you've understood
