A water cooler holds 1,284 ounces of water. How many more 6-ounce glasses than 12-ounce glasses can be filled from a full cooler

Lelu [443]

Just take them separately. so how many 6 oz glasses can you fill?

1284/6 = 214

how many 12 oz glasses?

1284/12 = 107

then find the difference between the two

214-107= 107

107 more glasses can be filled
