5 over 24.
[If you do not understand how to get that answer, here is how.
To subtract fractions you must find the common denominator. In this problem you must find the common denominator between 8 and 3.
They both can multiply into 24 so that is your common denominator. Now 8 times 3 will give you the denominator of 24, but you must also multiply the 7 by 3 to make the fraction the same. The first fraction will be 21/24.
The next fraction will be 16/24 because 2 times 8 is 16 and 3 times 8 is 24.
Now all that you have to do is subtract the numerators. 21 - 16 = 5 so your answer is 5/24.]
The answer is 3 over 7.
2 and 3/7 minus 8/14 = 13/7 or 1 and 6/7
-3 minus 7/2 is -6 1/2 or -6.5
7/8 minus 2/3 is 5/24
1 1/4 minus 2/3 is 7/12
1/2 minus 3/7 is 1/14
The answer is 3 over 7.
2 and 3/7 minus 8/14 = 13/7 or 1 and 6/7
6/14 minus 2/7 = 3/7 - 2/7 = 1/7
-3 minus 7/2 is -6 1/2 or -6.5
7/8 minus 2/3 is 5/24
2 minus 5 is -3, sooo your answer should be negative 3 over 7.
1 1/4 minus 2/3 is 7/12
1/2 minus 3/7 is 1/14
9/7 or 1 2/7
14
3 over 14
