Problem:
each deli sandwich made uses 1/4 pound of turkey. Tayler started 3 1/7 pounds of turkey and now has 1 5/8 pounds left. How many deli sandwiches did he make.?
Solution:
3 7/8 - 1/4x = 1 5/8
Change to improper fractions
31/8 - 1/4x = 13/8
Subtract 31/8 from both sides
-1/4 x = (13/8) - (31/8)
-1/4 = (-18/8)
Reduce (-18/8)
-1/4 x = (-9/4)
Multiply by -4 on both sides to clear the fraction
x = 9
He made 9 sandwiches
