24/13 - 9/13 = (24 - 9)/13 =15/13
11/15 minus 3/10 = 13/30
15 - 6 = 9 13 - 9 = 4 Therefore, 15 - 6 = 13 - 4.
21/30 - 8/30 = 13/30
9/10 - 13/30 = 27/30 - 13/30 = 14/30 = 7/15
Actually if we do the math the answer is 4.4. 9 4/15 (4/15 = .2666666) so we start with 9.2666666 minus 4 13/15 (13/15 = .8666666) and we end up with 4.4 9.2666666 - 4.8666666 = 4.4
2/3 is.
24/13 - 9/13 = (24 - 9)/13 =15/13
13/15 - 5/15 = 8/15
11/15 minus 3/10 = 13/30
11/15 − 3/10 = 13/30
[ (x - 4) / 15 ] / [(2x + 13) / 15] = (x - 4) / (2x + 13)
15 - 6 = 9 13 - 9 = 4 Therefore, 15 - 6 = 13 - 4.
21/30 - 8/30 = 13/30
9/10 - 13/30 = 27/30 - 13/30 = 14/30 = 7/15
3/10 - 11/15= 9/30 - 22/30 = -13/30
2/3 minus 12/15 is -2/15
