3. 3-34 a. 5/12 + 1/3

The given expression is a sum of two fractions: 5/12 and 1/3. To add these fractions, we need to find a common denominator, which in this case is 12. We then convert both fractions to have a denominator of 12. The first fraction becomes 5/12 and the second fraction becomes 4/12. Adding these fractions gives us a result of 9/12, which can be simplified to 3/4.

4. 3-34 b.4/5 + 3/4

The given expression is 4/5 + 3/4. To add these fractions, we need to find a common denominator, which in this case is 20. Multiplying the numerator and denominator of 4/5 by 4, we get 16/20. Multiplying the numerator and denominator of 3/4 by 5, we get 15/20. Now we can add the fractions: 16/20 + 15/20 = 31/20. This can be simplified to the mixed number 1 11/20. So, the answer is 1 11/20, 31/20.

6. 3-32. At Cassie's Cashew Shoppe, a sign says, "Today only: 20% off anything." Maribel realizes that she has a coupon for 1/5 off the price of anything in the shop. Which discount should she use, the 20%-off deal or the 1/5-off coupon? Does it matter?

20%-Off Coupon

1/5-Off Coupon

It doesn't matter. 1/5 is the same as 20%.

The answer is correct because 1/5 is equivalent to 20%. Therefore, whether Maribel uses the 20% off deal or the 1/5 off coupon, she will receive the same discount, and it does not matter which one she chooses.
