2 8/9

Explanation:

1)
i) First of all, we need turn all the mixed numbers and whole numbers (most commonly known as integers) into improper fractions (or top-heavy fractions as some might call them).

4 1/9 => 37/9

Remember to multiply the whole number by the denominator and add the numerator to the result.

eg: (4*9) + 1

ii) Turn 7 into an improper fraction.

7/1 => 63/9

2) Now that both denominators are equal. One simply has to subtract them.

(63-37)/9 = 26/9

3) All you need to do is convert this improper fraction to a mixed number.

26/9 => 2 8/9

Remember to divide the numerator by the denominator and to use the remainder as the new numerator.

eg: 26/9 is 2 remainder 8. So 2 is the whole number and the 8 is the numerator.

4 8/9

Explanation:

Remember that any whole number is made up of a number of equal parts. 8/8, 13/13, 5/5, 10/10 are all whole numbers equal to 1.

If you are subtracting a number of parts from a whole number, find how many parts are left.

8/8 - 1/8 = 7/8" "rarr" "8 parts - 1 part = 7 parts

11/11-3/11 = 8/11

23/23 - 10/23 = 13/23" "rarr 23 parts - 10 parts = 13 parts

3-1/7 = 2 6/7

19-3/11 = 18 8/11

5-3 1/5 = 5-3-1/5 = 2-1/5 = 1 4/5

SO in this case, subtract 4 from 7, then another 1/9

7-4 1/9 = 7-4-1/9

=5-1/9

4 8/9
