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

That depends on what you mean: twenty add one fifth is 20 + 1/5 = 20 1/5 twenty, add one fifth (of twenty) is 20 + 1/5 * 20 = 20 + 4 = 24
2/20 + 1/20 = 3/20

^^ Think. 1/10 x2 = 2/20. 2/20 + 1/20 = 3/20.

To add one quarter (1/4) and one fifth (1/5), you first need a common denominator, which is 20. Converting the fractions, 1/4 becomes 5/20 and 1/5 becomes 4/20. Adding these gives you 5/20 + 4/20 = 9/20. Thus, 1 quarter plus 1 fifth equals 9/20.
Convert the fraction to a decimal and then multiply by 100 and add a % sign. For example: 1/5 = 0.2 Multiply by 100: 20 Add % sign: 20% Thus 1/5 = 20%
