Oh, isn't that a lovely little math problem? Let's see here. First, we need to find a common denominator for 8 and 4, which is 8. So, 1/8 becomes 1/8 and 3/4 becomes 6/8. Adding those together gives us 7/8. Just like painting a happy little tree, sometimes all it takes is a little patience and the right tools to bring everything together beautifully.
1/8 plus 1/4 plus 1/2 = 7/8 or 0.875
3 over 8 plus -1 over 8 in fractional form is 2 over 8, or 2/8, and can be reduced to 1 over 4, or 1/4.
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
it equals 8 over 8 or 1 =1
1 1/8
3/8
3/8
1/2
9/8 or 1 and 1/8
The commutative property of addition.
8/18 plus 1/6 = 11/18
1/6 plus 3/8 is 13/24
