add:
2 1/2 + 3 1/4 + 3 5/8
I got 7 3/4
It can't be 7 3/4 because 2 + 3 + 3 = 8. The answer must be larger than 8.
2 1/2 = 2 4/8
3 1/4 = 3 2/8
3 5/8 = 3/5/8
Adding those together, I get 8 11/8 = 9 3/8
2 1/2 + 3 1/4 + 3 5/8
translated into decimals:
2.5 + 3.25 + 3.625 = 9.375 (fraction: 9 3/8)
To add the given mixed numbers, we need to convert them into improper fractions. Let's start by adding the whole numbers:
2 + 3 + 3 = 8
Now let's convert the fractions:
1/2 = (1 * 2 + 1) / 2 = 3/2
1/4 = (1 * 4 + 1) / 4 = 5/4
5/8 remains the same.
Now we can add the fractions:
3/2 + 5/4 + 5/8
To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 2, 4, and 8 is 8. Let's rewrite the fractions with a common denominator of 8:
(3/2) * (4/4) = 12/8
(5/4) * (2/2) = 10/8
Now we can add the fractions:
12/8 + 10/8 + 5/8 = (12 + 10 + 5) / 8 = 27/8
Therefore, the sum of 2 1/2, 3 1/4, and 3 5/8 is 27/8.
