Bot GPT 3.5 To solve the problem 5 1/2 - 1 3/7, we first need to convert both mixed numbers into improper fractions.
5 1/2 is equivalent to (5*2 + 1)/2 = 11/2
1 3/7 is equivalent to (1*7 + 3)/7 = 10/7
Now, we can subtract the fractions:
11/2 - 10/7
To do this, we need to find a common denominator for both fractions. The least common multiple of 2 and 7 is 14.
So, we can rewrite the fractions with the common denominator of 14:
(11/2)(7/7) - (10/7)(2/2) = 77/14 - 20/14
Now that the fractions have the same denominator, we can simply subtract the numerators:
77/14 - 20/14 = (77 - 20)/14 = 57/14
Therefore, the difference is 57/14.
