15 batches of cookies
Step-by-step explanation:
We need to find out how many third cups do into 5 cups. We can do this by 5 ÷ 1/3
When dividing fractions, use KFC:
- Keep the first fraction the same
- Flip the second fraction

To solve for x,
4.7x = 2.5x + 8.8
minus 2.5x from both sides:
2.2x = 8.8
divide both sides by 2.2:
2.2x/2.2 = 8.8/2.2
simplify:
x = 4
