Daughter is in 5th grade and I have no idea how to solve this math problem!
5 3/4 – 6 3/4
Obv you cannot subtract 5 from 6. You also can’t borrow the 3 from the 5 and make it a new mixed number. What do you borrow from? I’ve googled and seriously cannot figure this out.

The core problem that you are going to have here is that there’s 10 ways to solve this problem, but your daughter has likely only been taught one of those ways.
For me, how I would do it is to turn these mixed (whole number and a fraction) numbers into just fractions. So 5 and three quarters turns into 23/4 and 6 and three quarters turns into 27/4.
Next step would be to use cross multiplication to make a common denominator but that’s already the case here (the bottom part of the fraction is already the same.
So we have 23/4 – 27/4. When subtracting fractions with a common denominator you just substract the top part and leave the denominator the same in the result. SO 23-27= -4 so the overall answer is -4/4 and we can reduce that to -1.
That’s how I would solve the problem, but it’s been a LOOOOONG time since i was in 5th grade and they might be teaching newer methods now. It’s not that the answer would be different, it’s how you get there that might be different.
