The pet shop owner told jean to fill the new fish tank 3/4 full of water.Jean filled the tank 9/12 full.What fraction of the tank does she still need to fill?
she filled 3/4.. whe is done.
It would be 3/4. When you find the common denominator (which is 12) and you have to subtract 9/12 from 9/12 it would be 0/12, which isn't really a fraction, therefore she has filled it full.
To find the fraction of the tank that Jean still needs to fill, we can subtract the amount of water she already filled from the total amount the pet shop owner told her to fill.
The total amount the pet shop owner told Jean to fill the tank is 3/4.
Jean filled the tank 9/12 full, which is equivalent to 3/4.
To find the fraction that Jean still needs to fill, we can subtract the amount Jean filled from the total amount of the tank:
3/4 - 3/4 = 0/4.
Therefore, Jean doesn't need to fill any more of the tank since she has already filled it to the desired amount. The fraction she still needs to fill is 0/4.
To find the fraction of the tank that Jean still needs to fill, we first need to calculate the fraction of the tank that she has already filled.
Jean filled the tank 9/12 full. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3.
9/12 รท 3/3 = 3/4
So, Jean has filled the tank with 3/4 (or 9/12) of the required volume.
Now, let's calculate the fraction of the tank that still needs to be filled. We subtract the fraction of the tank that has already been filled from the total fraction (3/4) determined by the pet shop owner.
3/4 - 3/4 = 0/4
Since 0/4 is equivalent to 0, we can conclude that Jean doesn't need to fill any remaining fraction of the tank because she has already filled it completely.
