Julie has 4/3 cups of flour.She needs 2/5 cups of flour.How will she get the amount.
valentina_108 [34]

Answer:

Step-by-step explanation:

You need to set up a ratio for the original recipe and then use that ratio for the new one.

 

If we need 3 cups of flour for every 4 cups of sugar, we have a 3 c flour/4 c sugar ratio, or 3/4

 

The new ratio is 9 c of flour for ? c of sugar. Those ratios have to be the same, so we set up an equation like this:

 

3/4 = 9/?

 

In order to keep the same ratio, you have to multiply by the same number. Since 3*3 = 9, multiply 4*3 to get your answer.
