Answer:

99 dandelions

Step-by-step explanation:

Given: ratio of dandelions to peonies in the garden was 11 to 4

Total number of peonies in the garden = 36

To find: Total number of dandelions in the garden

Solution:

A ratio indicates number of times one quantity contains another quantity.

$\frac{Number\,\,of\,\,dandelions }{Number\,\,of\,\,peonies} =\frac{11}{4}\\\\\frac{Number\,\,of\,\,dandelions}{36} =\frac{11}{4}\\ Number\,\,of\,\,dandelions=(\frac{11}{4}) (36)=99$

So,

99 dandelions were there in the garden.
