Answer:
if you mean like 14/3. you would divide 14 by 3 which would give you 4 times which would equal 12 so you would have two left over that couldn't be divided by 4 and you have to keep the three so the answer would be 4 2/3. with 4 being the big number and 2/3 being the other half of the mixed fraction
The number of pairs of shoes each man can repair is its velocity time the time.
Call x the repair velocity of the assistant. Then, the repair velocity of the repairman is 2x.
So, the number of pairs of shoes that the assitant can repair in an 8 hour day is: x*8 = 8x
And the number of pairs of shoes that the repairman can fix in an 8 hour day is: 2x* 8 = 16x
As per the statement, 16x + 8x = 16
=> 24x = 16 => x = 16/24 = 2/3 of shoes in 8 hours.
That is the speed of the assistant, while the speed of the repairman is twice that = 4/3 in 8 hours.
So, divide 8 by 4/3 to determine the time to repair one shoe:
8 / ( 4/3) = 3 * 8 / 4 = 3 *2 = 6. That, is the repairman will take 6 hours to repair a pair of shoes.
Answer: 6 hours

Step-by-step explanation:
The BC/AD time line is like a number line: the negative side of 0, the numbers move backwards; and the positive side of 0 moves normally. If you have -25, then move to +25, you have just moved 50 places.
Hope this helps :)
