Each deli sandwich made uses 1/4 pound of turkey. Tyler started with 3 7/8 pounds of turkey and now has 1 5/8 pounds left. How many deli sandwiches did he make?

9 deli sandwiches, because 3 7/8-1 5/8 is 2 1/4 and 2 1/4 divided by 1/4 is 9

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
