Answer:
It will take 8 hours for the 5 workers to complete the same job.
Step-by-step explanation:
The amount of work done is the same for both crews.
Work = time * workers
Work = 10 * 4
Work = time * 5
Set the two equal
10 * 4 = time * 5
Divide each side of the equation by 5
10*4/5 = time *5/5
8 = time
This is a confusing question but I'm guessing an equivalent name for 57 is fifty-seven.
This is super simple, as it's just asking us to divide by 5.
5x=60
Divide both sides by 5, and we have our answer.
x = 12
If you encounter more questions like this, just look at it in a different perspective and it's really simple from there.
2/18
3/27
4/36
5/45
6/54
Take any number let's say 9
Then 9/9 = 1
Or 9/9 = 1/1
Then if you multiply the bottom half of those by 9, you get
9/9 becomes 9/81
and
1/1 becomes 1/9
So to generate any fraction equivalent to 1/9
take any number and write it as one, i.e. 5/5 = 1 (or 1/1)
and then multiply the bottom part by 9 = 5/45
