Amira has 3/4 of a bag of cat food her cat eats 3/8 of a bag per week how many weeks will the food last.

Hello,
We know that Amira's cat eats 3/8 of a bag per week, so

eat 3/8 of a bag in one week
eat 3/4 of a bag in ?week

Step 1:
Use cross multiply
3/4×1=3/4
Step 2:
3/4÷3/8=2 weeks. As a result, the food will last in 2 weeks. Hope it help!
