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.
In: 0
the thing to remember is that there is an implied ‘+’ between the whole number and the fraction.
5 ¾ means 5 whole and three quarters of a whole. You could write 5 + 3/4 to make it clearer, but usually we leave out the plus and treat the sum as number itself. We treat them like we would the number 5.75.
You can write your problem is: `5 + 3/4 – (6 + 3/4)` (the brackets are important because you subtract 6 and three quarters and don’t subtract 6 and then add three quarters.)
You can also write that as `5 + 3/4 – 6 – 3/4` or as `5 – 6 + 3/4 – 3/4` or `(5 – 6) + (3/4 – 3/4)` which works out to `-1 + 0 = -1`
You can also do it a number of different ways, which one is the one you are supposed to use here, depends on what your daughter last learned.
