Joe paid $25 for a $40 sweater, so we need to know what percent of 40 25 is.
25/40 is .625, or 62.5%. Subtract that from 100% and you get 37.5%, the answer to the question.


15% off would make the sweater $31, instead of $25.

ollegr [7]

Answer:

Step-by-step explanation:

1. Make 1 2/7 an improper fraction = 9/7

2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.

3. Add them together. 14/21+27/21=41/21.

4. (Optional) If the question is asking for mixed numbers, 41/21 = 1 20/21.
