Question

Genies is making cookies. She needs 1 2/3 cups of flour for one batch, but she wants to make 2 1/3 batches. Write an equation that can be used to find how many cups of flour genies will need

Answer 1

Equation: (1 2/3)(2 1/3) = x

Answer: 3 8/9 cups

Explanation:

x represents the amount of flour she will need in cups.

To solve, convert the mixed numbers to improper fractions and multiply...

1 2/3 becomes 5/3

2 1/3 becomes 7/3

Now we have

(5/3)(7/3) = x

35/9 = x

35/9 is 3 8/9 as a mixed number
