cc has 3/4 gallons of chocolate ice cream left from her birthday party. she ate 1/2 of the chocolate ice cream while watching tv. how much ive crea does she have left?

So you are going to do 3/4 - 1/2. find common denominators and subtract

3/4-1/2=

3/4-1/4=1/4

I got this by finding the common denominator of 4 and 2 and the common denominator was 4 so you multiply 3/4 by 1 and 1/2 by 2 and that's how you get 1/4

or 0.25

3/8 gallons left

Step-by-step explanation:

she has 0.75 of a gallon

she eats 0.5 (0.75) while watching TV

multiply 0.5 by 0.75 to get half of 3/4 of a gallon

0.375 of a gallon is what she has left

or 3/8 of a gallon
