Step-by-step explanation:
integer because is a negative number
"Common" means "same for both" or "same for all".
There's nothing common about a single item. There's no such thing
as a "common"factor unless there are at least two numbers.
Your answer would be 5/24. What you do is find the lowest common multiple (lcm) of both numbers that are alike. This is so you can be able to perform the subtraction. The lowest common multiple of 8 and 3 is 24. Now once you have the lowest common multiple you will find the fraction that is equal to both 7/8 and 2/3. 7/8 is equal to 21/24 and 2/3 is equal to 16/24. You may have caught on by now to what is going on. Here is the final step which is subtract the numbers. 21/24-16/24= 5/24. This fraction cannot be reduced anymore.

Answer:
Total time of the concert = 59.5 min = 59 minute 30 seconds
Explanation:
At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.
Total length of 8 songs = 4.25*8 = 34 min
Length of 3 songs = 2*4.25 = 8.5 min
Total length of 3 songs = 3* 8.5 = 25.5 min
Total time of the concert = 34 + 25.5 = 59.5 min = 59 minute 30 seconds
