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?

Respuesta :

Answer:

5 1/4 containers

Step-by-step explanation:

  • Let's call this chemical, chemical x, because memories
  • So Mr. Scientist has [tex]\frac{3}{4}[/tex] gallons of chemical x
  • So how many times does 1/7 gallons divide 3/4 gallons ?
  • That's [tex]\frac{3}{4} \div \frac{1}{7} = 5 \frac{1}{4}[/tex]
  • 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
