To solve the problem and express the sum or difference in simplest form, follow these steps:
Step 1: Find a common denominator.
The denominators of the fractions, 4 and 2, have a common multiple of 4. Therefore, we can rewrite the fractions with a common denominator of 4.
Step 2: Rewrite the fractions with the common denominator.
The first fraction, 5/4, already has a denominator of 4. The second fraction, 1/2, needs to be multiplied by 2/2 to obtain a denominator of 4. This gives us 2/4.
Step 3: Add or subtract the fractions.
Now that both fractions have a common denominator of 4, we can add or subtract them. In this case, we will add the fractions.
5/4 + 2/4 = 7/4
Step 4: Simplify the resulting fraction.
To simplify the fraction, we need to check if the numerator and denominator have any common factors. In this case, 7 and 4 have no common factors other than 1. Therefore, the fraction 7/4 is already in simplest form.
So, the sum of 5/4 and 1/2 is 7/4, which is already in simplest form.
