Answer:

480

Explanation:

Let x be the calories in 4 cups

Set it up

(90)/((3)/(4))=(x)/(4)

Step 1: Switch sides

(x)/(4)=(90)/((3)/(4))

Step 2: Apply fraction rule

$(x)/(4)=(90\cdot \:4)/(3)$

Multiply

(x)/(4)=(360)/(3)

Divide

(x)/(4)=120

Step 3: Multiply both sides by 4

$(4x)/(4)=120\cdot \:4\\\\=480$

There are 480 calories in 4 cups of the cereal.
