Cheryl is baking cookies for the bake sale. she buys 5 packages of chocolate chips, each with 1 3/5 cups in them. while baking, she uses 4 2/5 of chocolate chips. how many cups does she have left? (14 points)

5 x 1 3/5 = 8 cups

8 minus 4 2/5 equals 3 3/5 cup left

Total packaged purchased (5) multiplied by amount in each package (1 3/5), then subtract amount used (4 2/5).

=(5 * 1 3/5) - 4 2/5
=(5 * 8/5) - 22/5
=((5*8)/5) - 22/5
=40/5 - 22/5
=18/5
= 3 3/5 cups chips left

Check:
Total purchased=5 * 1 3/5 = 8

Amount used + Amount left=
=3 3/5 + 4 2/5= 8

Hope this helps! :)
