A chocolate chip cookie recipe requires one and two thirds cups of flour to one cup of chocolate chips. If three and three quarters cups of flour is used, what quantity of chocolate chips will be needed, according to the recipe?

2 1/4 cups of chocolate chips is required.

Step-by-step explanation:

chocolate chip cookie recipe requires one and two thirds cups of flour to one cup of chocolate chips. Converting 1 2/3 cups to improper fraction, it becomes 5/3 cups.

Also, converting three and three quarters cups(3 3/4) of flour to improper fraction, it becomes 15/4 cups.

Let x represent the quantity of chocolate chips that will be needed if 15/4 cups of flour is used.

Therefore,

If 5/3 cups of flour = 1 cup of chocolate,

then 15/4 cups of flour = x cups of chocolate.

Cross multiplying, it becomes

5/3 × x = 15/4 × 1

5x/3 = 15/4

x = 15/4 × 3/5

x = 9/4 = 2 1/4

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
