Answer: The answer is 3/8
Step-by-step explanation: First you figure out your expression: 7/8 - 1/2. Then you find a common denominator, which will be 8. To make one-half have a denominator of 8, multiply by 4/4. 1/2*4/4=4/8. To finish, subtract 7/8-4/8 and you get 3/8.
Twelve men take 6 hours to finish a piece of work.
In 1 hour, the 12 men will finish 1/6 of the work
( 1 job ) / ( 6 hrs ) = ( 1/6 of a job ) / ( 1 hr )
-----------------------------------------
That means there is of the job
left to do.
-------------------
If 12 men take 6 hours to finish a piece of work,
1 man will take 12 times as long, to finish the work, so
( 1 job ) / ( 6*12 = 72 hrs ) = rate of working for 1 man, or
-------------------
After 1 hour, there are a total of men working
20 men will work 20 times as fast as 1 man on the
of a job that remains, so
Let = hours for the 20 men to finish the job
