Question

Determine two mixed numbers with different denominators that have a sum of 3 4/5 and a difference of 3 4/5.

a. 2 3/4 and 1 1/5
b. 4 1/2 and 7 1/4
c. 5 2/3 and 1 1/15
d. 2 1/4 and 5 3/5

Answer 1

To find two mixed numbers with different denominators that have a sum and difference of 3 4/5, we can test the options using common denominators. Option a, 2 3/4 and 1 1/5, is the correct answer.

Step-by-step explanation:

To determine two mixed numbers with different denominators that have a sum and difference of 3 4/5, we can start by finding two fractions that add up to 4/5 and subtract to 4/5. Since the denominators need to be different, we can't use option d. By testing the options using common denominators, we find that option a, 2 3/4 and 1 1/5, satisfies the conditions.
