Subtraction with renaming
Am very confused. Am trying to teach my little brother but am getting everything wrong. I have the right answer but the work does not add up to that.
6  3 2/5
I got 3 2/5 but the answer is 2 3/5 I donâ€™t understand can you explain what I have to do so I can explain it to him in the most simpliest way.
5 1/4  2 3/4
I got 3 2/4 but the answer is 2 2/4 ?
I did 52 =3 then 3_1= 2/4
9 3/8  8 7/8
I got 1 4/8 but the answer is 4/8
12 3/10  7 7/10
I got 5 4/10 but the answer is 4 6/10
I donâ€™t understand I also have the lesson that was given but I still don’t understand it

hey
1. First subtract the integer portion. We have 63=3. Next, subtract the fraction. 32/5 = 2 3/5
2. Do the same thing. 5  2 = 3. 1/4  3/4 = 2/4. Now add the two. 3+2/4=32/4=2 2/4 or 2 1/2
3. 9  8 = 1. 3/8  7/8 = 4/8. Now we add the two. 1+4/8=14/8=4/8 or 1/2
4. 12  7 = 5. 3/107/10 = 4/10. Add the two: 5+4/10=54/10=4 6/10 or 4 3/5

6  3 2/5
First, change 6 to 5 5/5. Do you see how they're the same?

Now try the other problems.

6  3 2/5
we need to borrow 5/5 from the 6 You can not subtract 2/5 from nothing in this grade
5 5//5  3 2/5
2 3/5
========================
I suppose in a higher grade you could say
6  3 2/5 = 3 2/5
that is 2 3/5
but no one does it that waay
