Of course! I'd be happy to help you with adding and subtracting fractions. Here's a step-by-step guide on how to solve these types of problems:

1. Ensure that the fractions have the same denominator. If they don't, find the least common denominator (LCD). The LCD is the smallest multiple that both denominators have in common. For example, if you have to add 1/4 and 3/5, the LCD would be 20, since it is the smallest common multiple of 4 and 5.

2. Once you have the same denominator, you can add or subtract the numerators. Keep the denominator the same. For addition, simply add the numerators together.

Example: 1/4 + 3/4 = (1 + 3)/4 = 4/4 = 1

3. Simplify the fraction, if possible, by reducing it to its simplest form. To do this, find the greatest common divisor (GCD) of the numerator and the denominator, and divide both by it.

Example: 4/4 can be simplified to 1/1 because the greatest common divisor of 4 and 4 is 4, and dividing both the numerator and denominator by 4 gives us 1/1.

For subtraction, follow the same steps as above, but subtract the numerators instead of adding.
