Question

food A contains 150 calories in 3/4 of a serving. food B contains 250 calories in 2/3 of a serving. which food has fewer calories per serving?

Answer 1

I have the same problem on my homework :P

I finished mine in class...

I got food A has less cal because you divide 150 by 3 then to get 1/3 if 150 (which is 50) and add 50 to 150 to find the total calories which is 200.

For food B you do the same thing. You divide by three to get 1/3 and add that to 250. To get 375 cal which is more than food A :)

Answer 2

Food A has fewer calories per serving.

I found this by taking the first food (A) and dividing 150 by 3. This gave me 50, which I added onto 150 to give me my 4/4 of a serving (200 calories).

With food B, I did the same process. I took 250/2 and added that to the original amount to get the final third of the serving, which resulted in food B being 375 calories.
