If it takes 3/4 cups of sugar to make 1 batch of cookies, then how many cups of sugar does Fred need to make 4 or 1/2 batches?

Fred needs 3 cups of sugar to make 4 batches

Fred needs 3/8 cups of sugar to make 1/2 batches

Step-by-step explanation:

1 batch of cookies = 3/4 cups of sugar

how many cups of sugar does Fred need to make 4 batches

Let x = cups of sugar needed

Batches : Cups of sugar

1 : 3/4 = 4 : x

1 ÷ 3/4 = 4/x

1 * 4/3 = 4/x

4/3 = 4/x

Cross product

4 * x = 3 * 4

4x = 12

x = 12/4

x = 3 cups of sugar

Fred needs 3 cups of sugar to make 4 batches

how many cups of sugar does Fred need to make 1/2 batches?

Let x = cups of sugar needed

Batches : Cups of sugar

1 : 3/4 = 1/2 : x

1 ÷ 3/4 = 1/2 ÷ x

1 * 4/3 = 1/2 * 1/x

4/3 = 1/2x

Cross product

4 * 2x = 3 * 1

8x = 3

x = 3/8 cups of sugar

Fred needs 3/8 cups of sugar to make 1/2 batches

answer: can you me with homework?

step-by-step explanation:

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
