the pet shop owner told Jean to fill her new fish tank 3/4 full with water. Jean filled it 9/12 full. What fraction of the tank does Jean still need to fill??

9/12 = 3/4 * 3/3

3/3 = 1

SAme fraction, no more water.

3/4 = 9/12

3/3

9/12 because it is the same fraction.

none

I’m cool

9/12

Im smart so 0/12 because 9/12=3/4

Rename 9/12 and 3/4 then subtract so you get an answer.

3/4 9/12
