Answer:
7/12 cannot be reduced
Step-by-step explanation:
7 = 7
12 = 2 * 2 * 3
7 and 12 have no common factors other than 1, so the fraction 7/12 cannot be reduced. 7/12 is already written in lowest terms.
Multiply both sides by three to get 2x=30
Then divide both sides by 2 to get x=15
The answer is either a or d but we know she did all of this for more than 52 minutes.
