According to the directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice. How many 12 ounce cans of the can concentrate are required to prepare 200, 6-ounce servings of orange juice?

the answer is 25

Can someone please explain

ok .... so the total qty of juice is 1200 ounces... since the ratio of concentrate to water is 1:3 so concentrate = 300 and water = 900.... so total no. of 12 ounce cans required is 300/12= 25
