Question

Maria brought a bag that contained 16 cups of sugar she uses 2/3 cup of sugar each time she makes a batch of cookies if the bag now has 10 cups of sugar left how many batches of cookies has she made

Answer 1

To find the number of batches of cookies Maria has made, use a proportion: 2/3 cup / 1 batch = 10 cups / x batches. Solve for x to find the number of batches.

Step-by-step explanation:

To find the number of batches of cookies Maria has made, we need to use a proportion.

If she used 2/3 cup of sugar per batch, and there are 10 cups of sugar left in the bag, we can set up the proportion:

2/3 cup / 1 batch = 10 cups / x batches

Cross-multiplying gives us: 2/3 * x = 10

Dividing both sides by 2/3 gives us: x = 10 / (2/3)

Dividing 10 by 2/3 is the same as multiplying 10 by the reciprocal of 2/3:

x ≈ 10 * (3/2) = 15

So, Maria has made approximately 15 batches of cookies.
