Answer:
20 over 3
Step-by-step explanation:
First you make the fractions top heavy instead of mixed numbers, so:
5/2 × 16/5
Then you just multiply across:
5 × 16 = 80
2 × 5 = 10
Your answer is 80/10, which can be simplified to 8.

Answer:
Step-by-step explanation:
Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.
15% of 52 is indeed 7.8. $7.80 is the discount that is to be SUBTRACTED from the regular price ($52). Adding $7.80 to $52 is incorrect.
Also, 52 + 7.8 - 59.8 is incorrect: it's not an equation (but should be one), and we should be subtracting $7.80 from $52.
