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).

419379

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

eg: (49)+1

ii) Turn 7 into an improper fraction.

71639

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

63379=269

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

269289

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

eg: 269 is 2 remainder 8. So 2 is the whole number and the 8 is the numerator.

Explanation:

Remember that any whole number is made up of a number of equal parts. 88,1313,55,1010 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.

8818=78 8 parts - 1 part = 7 parts

1111311=811

23231023=1323 23 parts - 10 parts = 13 parts

317=267

19311=18811

5315=5315=215=145

SO in this case, subtract 4 from 7, then another 19

7419=7419

=519
