To estimate the sum of 3 1/5 + 2 1/2, we can first convert the mixed numbers to improper fractions and then add them together.
Converting 3 1/5 to an improper fraction:
3 * 5 = 15
15 + 1 = 16
So, 3 1/5 can be written as the improper fraction 16/5.
Converting 2 1/2 to an improper fraction:
2 * 2 = 4
4 + 1 = 5
So, 2 1/2 can be written as the improper fraction 5/2.
Now, we can add the fractions:
16/5 + 5/2
To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 5 and 2 is 10.
Multiplying the numerator and denominator of 16/5 by 2:
(16 * 2) / (5 * 2) = 32/10
The addition becomes:
32/10 + 5/2
Now, we can add the fractions by finding a common denominator of 10:
(32 + 25) / 10 = 57/10
To estimate the sum, we can round 57/10 to the nearest whole number, which is 6. So the estimated sum of 3 1/5 + 2 1/2 is approximately 6.
Therefore, the answer is A. 6.
