Three fourths minus five tenths is one fourth.
five and a half(I took a short cut: seven and five fourths minus two and three fourths... seven minus two & five fourths minus three fourths)
The answers is: 7 and 1/8 minus 2 and 3/4 = 4 and 3/8
turn 8 into 8 over 8 and solve from there.
3 eighths. three fourths is the same as six eighths, so subtract your 3/8 and you have 3/8 left
3/4 - 3/8 = 6/8 - 3/8 = 3/8
3/4 - 2/5 = 15/20 - 8/20 = 7/20
8 & 2/3 - 3/4 = 8 & 8/12 - 9/12 = 7 & 11/12
3/4 - 1/8 = 5/8
7 fourths minus 8 fifths = -1
I think the answer is 8
3/8
