Carlota has 3/4 ton of mulch she is going to divide evenly among 5 flower beds. how much mulch will each flower bed contain? show work

The first thing to do is to turn 5 into a fraction.  
5 = 5/1

Now it is just a simple fractional division question: 
3/4 / 5/1

With fractional division, all you do is switch around the fraction that is on the right and turn the divide sign into a multiplication sign: 
3/4 X 1/5

Now you simply multiply the numerators together, and the denominators together: 
3 X 1 = 3
4 X 5 = 20

3/20. 

Each flower bed will contain 3/20 of a ton of mulch.
