6 - 5/3 is how it should be written out. To solve this problem, you must first turn 6 into a fraction as well, which is easily done by multiplying 6 by 3 which gives you 18, and then placing the value by which you multiplied by as the denominator, since 18 divided by 3 equals 6.
It should now look like this: 18/3 - 5/3=
Now, you subtract the numerators, the top numbers, from each other.
18/3 - 5/3= 13/3
Since 13/3 cannot be simplified that is your answer.
If you require a mixed number you take you divide 13 into 3. 3 goes into 13 four times. You cannot simply throw away the rest of the number, so you place it next to 4, so it would be 4 and 1/3.
To double check if you did it right, multiply the denominator, the bottom number, in your fraction by the whole number and then add the numerator.
-5 and two thirds.
6 minus 3 and two thirds = 2 and one third.
12 - 5 2/3 = 6 1/3
5/6 - (-2/3) = 5/6 + 2/3 = 5/6 + 4/6 = 9/6 = 1 1/2

4 and 1/6
3 and 5/6
2/3 minus 6/5 is -8/15
38/6 - 15/6 = 23/6 or 3 and 5/6
5/3 minus 1/2 is 1 1/6
6 minus 3 and two thirds = 2 and one third.
1 and 5/6
12 - 5 2/3 = 6 1/3
5/6 - 2/3 = 1/6 or one sixth
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
