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?
E = 51
1.7 R = E
30
To find the number of plants Rosalie has in her garden, we need to know how many plants Elizabeth has in terms of a whole number. Let's convert the mixed number 1 7/10 to an improper fraction.
1 7/10 = (1 * 10) + 7/10 = 10/10 + 7/10 = 17/10
Now that we have the fraction, we can set up a proportion to find the number of plants Rosalie has.
Let R be the number of plants Rosalie has:
17/10 = 51/R
To solve the proportion, we can cross-multiply:
17R = 10 * 51
17R = 510
Dividing both sides by 17:
R = 510/17
R ≈ 30
Rosalie has approximately 30 plants in her garden.
