1/7 + 2/14 = 4/14
5/10 + 10/20 = 1
1/4 + 1/24 = 7/24
5/20 + 1/10 = 7/20
9/18 + 1/36 = 19/36
1/2 + 1/4 = 3/4
3/4 + 1/2 = 1 1/4
1/3 + 7/12 = 11/12
5/100 + 5/1000 = 55/1000
7/20 + 3/10 = 13/20
I don't think you need 20 examples, it's blatantly obvious the process involved.

Negative 15 minus 5 can be solved by subtracting 5 from -15. This results in -20, as subtracting a positive number from a negative number increases the magnitude of the negative value. In mathematical terms, -15 - 5 = -20.
Examples of fractions that are equal to 15/20 are 3/4, 6/8, 9/12.
Say you have 5 and 1/10 and you have to add 6 and 3/20, you add the whole numbers, (11) and then convert the 10 of 1/10 to 20 (20/10 is 2), then you have to multiply the 1 by 2 to get 2/20 (equivalent fraction of 1/10). Now you can add the fractions, i.e. 4/20 (or simplified, 1/5). Final answer is 11 and 1/5
I'll make up an example problem; 2 3/5 - 1 1/4. First get your terms into fraction form 2 3/5 = 13/5 and 1 1/4 = 5/4 so our problem becomes 13/5-5/4 next find the least common denominator ( in this case 20 ) 52/20 - 25/20 = 27/20 then simplify 27/20 = 1 7/20
200/8 and 2020/808 are two examples.
150/200 and 150000/200000 are two examples.
200/900, 100/450, 22/99 are some examples.

fractions of 20 = 20/1, 40/2, 60/3, 80/4,...
Because subtracting a negative number is the same as adding a positive number. Subtracting -20 is the same as adding +20. 31 - (-20) = 31 + 20 = 51
460.00 - 20% = 368.00
When adding or subtracting fractions where the denominators are different. Convert the fractions to a common denominator. Sometimes it is possible to operate on the integers separately to the fraction part but it is good practice to convert mixed numbers into improper fractions. 3²/₅ - 1¼ = 17/5 - 5/4 The common denominator of 5 and 4 is 20. (4 x 17) - (5 x 5) ÷ 20 = (68 - 25) ÷ 20 = 43/20 This can be converted to the mixed number 2 and 3/20
