Step-by-step explanation:

Answer 2

9514 1404 393

Answer:

  yes

Step-by-step explanation:

Each of the two lengths is more than 1/2, so their sum will be more than 1.

  8/12 > 6/12

 7/8 > 4/8

(8/12) +(7/8) > (6/12) +(4/8) = 1/2 + 1/2 = 1

8/12 + 7/8 > 1

The total length of wire is greater than 1 foot, so Sam and Lou have enough for the project.

_____

If that sort of estimate doesn't work for you, then you can add the numbers to see what their total is.

  8/12 +7/8 = 16/24 +21/24 = 37/24 = 1 13/24 > 1
