First you have to make the same denominators: Find the lowest number that 7 and 3 both go into which is 21. So multiply the denominator by the number that makes 21 on both 2/7 and 1/3. Make sure to multiply the number you used on den. on the numerator to. Here are the new fractions: 6/21 and 7/21 Then subtract as normal. Answer would be negative 1/21 or -1/21
negative 1 over 3
1 over 2
2/5 minus 1/15 is 1/3
3/6 minus 2/8 is 1/4
It is: 1 -2/3 = 1/3
3/2 minus 1/5 = 1 3/10
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
1/2 minus 3/7 is 1/14
negative 1 over 3
1 and 1 over 3
1 and 2/3
1 over 2
3/2 minus 2 equals -1/2
1 1/2
2 and 1/12 minus 1 and 1/3 = 3/4 or 0.75
2/5 minus 1/15 is 1/3
1 over 2
