Math Problem of the Week - Upper Elementary - Nov. 14, 2021 to Nov. 20, 2021

Upper Elementary: 

Question: Three-fourths of a cannister of toxic ooze spills into a sewer. If 4½ fluid ounces of ooze is left inside the cannister, then how much ooze does the cannister hold in total?

Answer:  18 fluid ounces

Solution:  Since ¾ of the cannister of ooze spilled, that means that 4½ fluid ounces is ¼ of the total amount of ooze the cannister can hold. So, the cannister can hold 4½ × 4 = 18 fluid ounces in total.
