Question

An science teacher had 3/4 gallons of a chemical to pour into containers. If he poured 1/7 gallon into each container until he ran out of paint, how many containers had chemical in them, including the one that was partially filled?

Answer 1

5 1/4 containers

Explanation:

• Let's call this chemical, chemical x, because memories
• So Mr. Scientist has
  `(3)/(4)` gallons of chemical x
• So how many times does 1/7 gallons divide 3/4 gallons ?
• That's
  `(3)/(4) / (1)/(7) = 5 (1)/(4)`
• So only 5 and a quarter containers have chemical.
• The one that was partially filled is either empty or is one of the 5 1/4 containers with chemical x in it
