A cookie recipe calls for 1 1/4 cups of flour and 1 1/2 cups of sugar. If the amount of the ingredients are increased proportionally and the amount of sugar was increased to 9 cups, how many cups of flour would be needed?

7.5 cups of flour would be needed

Step-by-step explanation:

Here, we shall be making a ratio comparison.

To do this, it is best we use decimal notations.

The ratio of cups of flour to cups of sugar in decimal notation would be ;

1.25 to 1.5; This ratio is 1 to 1.2

Now, we have sugar increased to 9 cups; thus let the cup of flour be x

Using the ratio comparison;

1:1.2 = x:9

1/1.2 = x/9

1.2x = 9

x = 9/1.2

x = 7.5

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
