Answer:
13.5 hours
Step-by-step explanation:
If it takes Amy 12 hours to complete the job alone
And it takes Tom 15 hours to complete the same job alone,
How long will it take for both of them to get the job done together?
Amy= 12 hours
Tom= 15 hours
Amy + John =?
(12 + 15)/ 2
27/2= 13.5 hours.
So it would take Amy and Tom 13.5 hours to complete the job together.

We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.
In order to find out the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.
Now we can find out out our desirable ratio by substituting our finding in the ratio.
Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.
