Answer: C, 2 2/8
Step-by-step explanation: To turn a mixed number into an improper fraction, multiply the whole number by the denominator. Then, add the numerator. So in this example it would be:
4 3/8 = 35/8
2 1/8 = 17/8
Now, since the denominators are equivalent, all we need to do is subtract the numerators.
35/8 - 17/8 = 18/8
The answer needs to be changed back to a mixed number. For this problem, there is an easy way to do this.
18/8 = 8/8 + 8/8 +2/8, which as a mixed number would be 2 2/8.
So the correct choice would be (C).
