Ihave a container of peanuts and i give 1/4 to my sister and 1/3 to another sister. what fraction do i keep?

Find a common denominator.
we'll pick 12 so...
1/4 = 3/12
1/3 = 4/12

So you gave your sisters

3/12 + 4/12 = 7/12

You keep 12/12 - 7/12 = 5/12

The answer is 25uthere is no v in the question

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
