Answer 1

Answer:

1) 7 burgers

2) 5/8 pounds

3) 5 pounds total

4) 20 burgers

Step-by-step explanation:

1) The key phrase is "at least" 3/8. That means we include not only the one burger that weighed 3/8 pounds, but all that weighed more as well! Add up all the burgers that were 3/8 or more pounds:

    1 + 4 + 2 = 7

2) The heaviest burger weighed 3/4 pounds. The lightest burger weighed 1/8 pounds.

   3/4 - 1/8 =

Find the least common denominator, which is 8. Multiply 3/4 by 2:

   6/8 - 1/8 = 5/8

3) Add up all the burgers.

   1/8 + 4(1/4) + 3/4 + 4(1/2) + 2(3/4) = 5 pounds.

4) We need to divide the total weight by 1/4 to get the number of burgers she could make.

    5 / 1/4 is the same as 5 * 4/1 = which is 20 burgers.

    She can make 20 burgers that weigh 1/4 pound each.

Answer 2

Answer:

1. 7

2. 5/8

3. 5

4. 20

Step-by-step explanation:

There is one burger that weighs 3/8 pounds, four that weigh 1/2 pound, and two that weigh 3/4 pounds. The difference between the heaviest and the lightest is 3/4-1/8=5/8. The total combined weight is 5 pounds. 5/ 1/4= 5*4=20. Hope this helps!
