Food a contains 150 calories in 3/4 of a serving. food b contains 250 calories in 2/3 of a serving. find each unit rate. which food has fewer calories per serving?

The unit rate is going to be calories per servingcalories / serving

Food A :
150 / (3/4) =
150 * 4/3 =
600/3 =
200 calories per serving

Food B :
250 / (2/3) =
250 * 3/2 =
750/2 =
375 calories per serving

Therefore, Food A has fewer calories per serving <==

25 is obviously the correct answer
