Jordon has 56 DVDs. That is 4/5 of what Joseph has. You want to find the rate, or how many DVDs there are at 1/5, to make it easier to find how many Jospeh has. Divide by four since it is 4/5s
56/4= 14
All you have to do is multiply that by 5. Because 1/5. You want to find 5/5.
14*5= 70 DVDs
I hope this helps!
