Two questions.

1. Jordan has 4/5 as many DVDs as Joseph. If Jordan has 56 DVDs, then how many does Joseph have?

I did this and are my steps correct?

4/5 x 1/56 = 4/224

Then I divide 4/224 = 56



2.Elizabeth has 1 7/10 as many plants as Rosalie has in her garden. If Elizabeth has 51 plants, how many plants does Rosalie have in her garden?


17/10 x 1/51 = 17/510 = 30 plants


What am I doing wrong on these??

  • Math 6 -

    * = multiplication

    Let X= Rosalie. The first equation should read as
    followed: (4/5)*X=56

    Solve for X. Which should give you 70 DVDs.

    Let X=Elizabeth. The second equation should read as followed: (17/10)*X= 51

    Solve for X. Which should give you 30 plants.
