Add the following fractions: Change Improper Fractions and Simplify where needed. When typing fractions, use the / key (it is next to the 'shift' key). Example: 1/2 = one half.
- A.
  
  3/4
- B.
  
  3/8
Correct Answer
A. 3/4

Explanation
The given question asks to add the fractions 3/4 and 3/8. To add fractions, we need to have a common denominator. In this case, the common denominator is 8. We can convert 3/4 to an equivalent fraction with a denominator of 8 by multiplying both the numerator and denominator by 2. This gives us 6/8. Now, we can add 6/8 and 3/8 together, which equals 9/8. However, since 9/8 is an improper fraction, we need to simplify it. Dividing both the numerator and denominator by their greatest common divisor, which is 1, we get the simplified fraction 9/8.

Subtract the following fractions: Change Improper Fractions and Simplify where needed When typing fractions, use the / key (it is next to the 'shift' key). Example: 1/2 = one half.

Correct Answer
1/4

Explanation
To subtract fractions, we need to have a common denominator. In this case, both fractions already have the same denominator, which is 4. Therefore, we can subtract the numerators directly. 1 minus 0 is 1. So the result is 1/4.
