C=A/B/D the slashes mean divide btw
Let's assume the number be x.
So, product of seven and a number can be written as 7*x.
Now the given statement is “One-fifth less than the product of seven and a number” which means we need to take out 1/5 from 7x. Hence, it can be converted into an algebraic expression as follows:
The easiest way for me to do this is by the mins.
There are 60 mins in 1 hour so do 36 x 60
then add 45
so you're working with 2,205 mins. So let's divide by the 3 men instead...
735 now lets reverse engineer this...
735 / 60(mins)
12 hours 25 mins...
now lets add that to our original....
49 hours and 5 mins.
I could be wrong but as far as I'm looking at it seems like a good way to answer. anyone is welcome to check my work.
Another way to look at this is the same 2205 mins, but as a fraction 5/5 3/5
3/5 is .60 percent of 5/5 so multiply 2205 by .60
264.6
now divide by 60 4.41
Now add to first...
41 hours 43 mins
