To find out how many cups of sugar you will need for 81 brownies, you first need to determine the ratio of sugar to brownies.

In the given scenario, you made 9 brownies using 1 cup of sugar. This means that the ratio of brownies to sugar is 9:1.

To find out how much sugar you need for 81 brownies, you can set up a proportion using this ratio:

9 brownies / 1 cup of sugar = 81 brownies / x cups of sugar.

Simplifying the proportion, you get:

9/1 = 81/x.

To find the value of x (the amount of sugar needed for 81 brownies), you can cross-multiply and solve for x:

9x = 81 * 1.

9x = 81.

Divide both sides of the equation by 9:

x = 9.

Therefore, you will need 9 cups of sugar for 81 brownies.

Answer 3

To determine the amount of sugar needed for 81 brownies, we can use a ratio.

First, we need to find the ratio of brownies to sugar in the original recipe. In the original recipe, 9 brownies were made with 1 cup of sugar. Therefore, the ratio of brownies to sugar is 9:1.

To find out how many cups of sugar are needed for 81 brownies, we can set up a proportion using the ratio:

9/1 = 81/x

Here, x represents the unknown number of cups of sugar needed for 81 brownies.

To solve this proportion, we can cross multiply:

9 * x = 81 * 1

Simplifying:

9x = 81

Now, we can solve for x by dividing both sides of the equation by 9:

x = 9

Therefore, you would need 9 cups of sugar to make 81 brownies.
