one batch of cookies requires 2 and 2/3 cups of sugar how much sugar does Angela need if she wants to make one and a half batches

4 cups of sugar

Step-by-step explanation:

To solve this, you need to multiply 2 2/3 by 1 1/2. To do this, you need to change both into improper fractions:

2 2/3 --> 8/3

1 1/2 --> 3/2

Now, you need to multiply them together:

8/3 x 3/2

= 24/6

= 8/2

= 4 cups of sugar

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

853.3
