Answers
GPT 3.5
To add 15 2/3 and 12 3/4 as a mixed number, you first need to find a common denominator for the fractions. The least common multiple of 3 and 4 is 12. Now, convert both fractions to have a denominator of 12.
15 2/3 = 15 * 3/3 + 2/3 = 45/3 + 2/3 = 47/3
12 3/4 = 12 * 4/4 + 3/4 = 48/4 + 3/4 = 51/4
Now, add the two fractions:
47/3 + 51/4 = (47 * 4 + 51 * 3) / (3 * 4) = (188 + 153) / 12 = 341/12
The sum of 15 2/3 and 12 3/4 as a mixed number is:
28 5/12
15 2/3 = 15 * 3/3 + 2/3 = 45/3 + 2/3 = 47/3
12 3/4 = 12 * 4/4 + 3/4 = 48/4 + 3/4 = 51/4
Now, add the two fractions:
47/3 + 51/4 = (47 * 4 + 51 * 3) / (3 * 4) = (188 + 153) / 12 = 341/12
The sum of 15 2/3 and 12 3/4 as a mixed number is:
28 5/12
whats 15 2/3 + 21 3/4 as a mixed number
GPT 3.5
To add 15 2/3 and 21 3/4 as a mixed number, we first convert both mixed numbers into improper fractions.
15 2/3 = (15 * 3 + 2) / 3 = 47/3
21 3/4 = (21 * 4 + 3) / 4 = 87/4
Now, we add the two fractions:
47/3 + 87/4
Since the denominators are different, we need to find a common denominator. The least common multiple of 3 and 4 is 12, so we convert both fractions to have a denominator of 12.
47/3 = (47 * 4) / (3 * 4) = 188/12
87/4 = (87 * 3) / (4 * 3) = 261/12
Now, we can add the fractions:
188/12 + 261/12 = (188 + 261) / 12 = 449/12
The sum of 15 2/3 and 21 3/4 as a mixed number is:
37 1/12
15 2/3 = (15 * 3 + 2) / 3 = 47/3
21 3/4 = (21 * 4 + 3) / 4 = 87/4
Now, we add the two fractions:
47/3 + 87/4
Since the denominators are different, we need to find a common denominator. The least common multiple of 3 and 4 is 12, so we convert both fractions to have a denominator of 12.
47/3 = (47 * 4) / (3 * 4) = 188/12
87/4 = (87 * 3) / (4 * 3) = 261/12
Now, we can add the fractions:
188/12 + 261/12 = (188 + 261) / 12 = 449/12
The sum of 15 2/3 and 21 3/4 as a mixed number is:
37 1/12
