Question

Sam drove 6 1/2 hours on Saturday and 8 2/3 hours on Sunday. How much longer was his drive on Sunday than on Saturday?

Answer 1

The answer is 2 and 1 6th because you need to find the common factor which is 6 and multiply 2/3 by 2 and 1/2 by 3 subtract and their is your answer.

Answer 2

Based on the phrase "how much longer" this is going to be a subtraction problem
8 2/3 - 6 1/2
Steps:
1. Find the least common denominator. Both 3 and 2 have a multiple of 6
2. Multiply 2/3 by 2 (numerator and denominator) and 1/2 by 3 to get an overall denominator of 6
8 4/6 - 6 3/6
3. Now you can do basic subtraction. Subtract the whole numbers
           8-6= 2
 4. subtract the numerators
        4-3=1
Answer is 2 1/6
