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??

* = multiplication
Let X= Rosalie. The first equation should read as
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.

For answer 1. Solve 56 x 5/4.
When multiplying a fraction by a whole number,
write the whole number as a fraction over 1
look for factors to simplify the multiplication
multiply the numerators
multiply the denominators
write the product as a fraction in simplest form.
For answer 2. Solve 1 & 7/10x=51
Dividing with mixed numbers is similar to multiplying mixed numbers in that you need to convert the mixed numbers to improper fractions. Dividing with mixed numbers is similar to dividing with fractions in that you first need to find the reciprocal of the second fraction.
To divide with mixed numbers, follow these steps:
Change the mixed number(s) to improper fraction(s).
Identify the reciprocal of the second fraction.
Here are some tips to dividing with mixed numbers:
• Look for factors to simplify the multiplication.
• Multiply the numerators.
• Multiply the denominators.
• Write the product as a fraction in simplest form.
