If 1/4 cup of brown rice is 160 calories, how many calories would be in 1 cup?

Just think for a moment -- You have 1/4 of a full cup. A full cup would be 4 times as much and hence 4 times as many calories.

Answer:
640 calories

P.S. (In actuality, a 1/4 cup of rice is only about 54 calories and a full cup is about 216 calories.)

160 / (1/4) = x / 1...find x...known cal / (1/4) cup is same as unknown cal / 1 cup

160 calories x 4 = 640 calories.

1 cup equals 4 quarter cups or 640 calories.

probably 640, you just do 160 x 4

1/4 cup x 4 = 1 cup.

160 x 4 = 640 calories

2 pts for me and -5 for u

(1/4)/160 = 1/x

1/4x = 160

x = 640 calories..//

"for future reference"
Ha!
What this means is "do my homework".

1/4 x 4 = 4/4 = 1
160 x 4 = 640 calories
