It takes Gary 1 hour to milk all the cows, and it takes Dana 1.5 hours. How long will it take them to do the job together? Please explain all the steps and models/equations used. Thanks so much.
Answers
It takes Gary 1 hour to milk all the cows. 1 hour per job ==> 1 job per hour.
It takes Dana 1.5 hours. 1.5 hour per job ==> 1/1.5 job per hour.
Working together, they can do (1/1 + 1/1.5) job per hour.
To add these fractions, put them over a common denominator:
First you make 15 a fraction by putting it over 1. Then you make 6 2/3 a mixed fraction. To do this, you multiply 6 with 3 and add 2 to it. Then you put the number over 3. We get 6 X 3 = 18 18 +2 = 20 20/3
Now, we divide 15/1 with 20/3. When we divide it, we actually cross multiply it. Basically, we flip the fraction and multiply it.
So we get 15/1 X 3/20 = .
We get 45/20 which can be simplified to 9/5 which can be simplified to 2 1/4.
So the answer is 9/4 or 2 1/4.
If you would like to know what is 15 divided by 6 2/3, you can calculate this using the following steps:
6 2/3 = 20/3
15 / 20/3 = 15 * 3/20 = 45/20 = 9/4 = 2.25
Result: 15 divided by 6 2/3 equals to 9/4.
