To find the sum or difference of fractions, you need to follow these steps:

Step 1: If the fractions have different denominators, find their least common multiple (LCM) of the denominators. This will be the new denominator for both fractions.
Step 2: Convert each fraction to have the same denominator by multiplying each numerator and denominator by the appropriate factor.
Step 3: Once the fractions have the same denominator, you can perform the addition or subtraction of the numerators.
Step 4: Simplify the resulting fraction if possible.

Let's apply these steps to each problem:

1. 5/10 - 3/10:
The fractions already have the same denominator, so we can subtract the numerators directly:
(5 - 3) / 10 = 2/10 = 1/5

2. 1/2 + 3/4:
The fractions have different denominators. The LCM of 2 and 4 is 4.
Convert 1/2 to have a denominator of 4: (1/2) x (2/2) = 2/4.
Now we can add the fractions: 2/4 + 3/4 = 5/4.
The fraction 5/4 is an improper fraction, so we can convert it to a mixed number if desired: 1 1/4.

3. 1/6 + 3/8:
The fractions have different denominators. The LCM of 6 and 8 is 24.
Convert 1/6 to have a denominator of 24: (1/6) x (4/4) = 4/24.
Convert 3/8 to have a denominator of 24: (3/8) x (3/3) = 9/24.
Now we can add the fractions: 4/24 + 9/24 = 13/24.

4. 7/8 - 5/12:
The fractions have different denominators. The LCM of 8 and 12 is 24.
Convert 7/8 to have a denominator of 24: (7/8) x (3/3) = 21/24.
Convert 5/12 to have a denominator of 24: (5/12) x (2/2) = 10/24.
Now we can subtract the fractions: 21/24 - 10/24 = 11/24.

5. The sum of two numbers is 7/8. One addend is 3/4. What is the other?
Let x be the unknown addend.
We can write the equation: 3/4 + x = 7/8.
To solve for x, we need to isolate it on one side of the equation.
Subtract 3/4 from both sides: x = 7/8 - 3/4.
Applying the same steps as before, we find the common denominator, which is 8.
Convert 7/8 to have a denominator of 8: (7/8) x (1/1) = 7/8.
Convert 3/4 to have a denominator of 8: (3/4) x (2/2) = 6/8.
Now we can subtract the fractions: 7/8 - 6/8 = 1/8.
Therefore, the other addend is 1/8.
