butter and flour are mixed in the ratio 2:3. paul has 640 grams of butter and 880 grams of flour. how much more flour does he ne

Answer:

80 grams

Step-by-step explanation:

Here's the breakdown:

The ratio of butter to flour is 2:3, meaning butter grams divided by flour grams equals 2/3.

We use the proportion:

2/3 = 640/x (where x is the grams of flour needed)

Solving for x gives:

x = 960 grams

This is the total amount of flour needed to maintain the ratio. Given Paul already has 880 grams of flour, the additional amount required is:

x + 880 = 960 grams → x = 80 grams
