Answer: What percentage of time did she spend practicing ballet?
Answer:
Concept: Percentage Addition
- Your original price is 7.70
- It increased by 60%
- Hence you do 7.70 * .60 = x
- Whatever you get from (3) you add it to 7.70+x to get your final price
The answer is B because the LCM of 8 and 9 is 72, which changes 4 5/8 to 4 45/72 and 2 2/9 to 2 16/72. 45/72+16/72 is 61/72 and then add the whole numbers.
