It seems like there's a bit of confusion in your question. However, I'll try to explain the concepts of substitution and adding fractions separately.

1. Substitution in mathematics: This is when you replace a variable (like x or y) with a specific number. For example, if you have an equation like x + 2 = 5, you can substitute x with 3 to make the equation true.

2. Adding fractions: To add fractions, you need to have a common denominator. For example, if you're adding 1/4 and 2/4, you can simply add the numerators (the top numbers) to get 3/4. If the denominators are different, like 1/3 and 1/2, you need to find a common denominator first. In this case, the common denominator is 6, so you would convert the fractions to 2/6 and 3/6, then add them to get 5/6.

If you're talking about substituting fractions with whole numbers in an equation, you would simply replace the fraction with the whole number. For example, if you have an equation like x + 1/2 = 3, you could substitute x with 2.5 to make the equation true.
