Question

20% of the roses Annette picked from a rose garden were red. If she picked 10 red roses, how many roses did she pick from the garden? A.50 roses B.40 roses C.30 roses D.20 roses

Answer 1

For this case we can make the following rule of three:
 20% -------------> 10
 100% -----------> x
 From here, we clear the value of x:
 $x = ((100) / (20)) * (10)$
 Calculating the value of x we have:
 $x = 50$
 Therefore, Anette collected 50 roses from the garden.
 Answer:
 she did pick 50 roses from the garden
