I don't get this:

Arya makes cupcakes at a bakery. She needs 2 cups of sugar for every 3 cups of flour. She needs 5 cups of flour to make a day's worth of cupcakes.

How many cups of sugar will she need? (Round your answer to the nearest tenth.)

Can you please help?

You can use a proportion.

2/3 = x/5

Cross multiply and solve for x.
31/3
