Ne serving of ice cream has 140 calories and a mass of 60 grams.
Paha777 [63]

Answer:

35 Calories

Step-by-step explanation:

15 is 1/4 of 60

60/15 = 4

140/4 = 35

Since 15 is 1/4 the size of 60, the number of calories will be 1/4 the amount as well. That is why you divide 140 by 4 to find the total calories for the mass of 15.

Brenda is making a dessert that takes 3.5 hours to prepare. If she wants to be finished by 1:15, at what time should she start??
dusya [7]
3.5 hours is 3 hours and 30 minutes.
1:15 is 1 hour and 15 minutes. 

The question is asking at what time does she want to start and end up at 1 hour and 15 minutes? SO you add the time it takes for her to make the dessert with the time at which she ends.

TLTR?? 4:45
