Sagot :
The answer is 17, because you know it’s going to be most of it, so you do 20 times .85 on your calculator, and you have your answer! :)
Method 1
We can find the number of Devon's movie collection by multiplying its percentage by the number of Action movies. That is;
Number of Devon's movie collection [tex]= \frac{85}{100} \times 20=\frac{85}{5} =17[/tex]
Method 2
We can also use ratio and proportion. According to the question, out of every 100 Action movies 85 are Devon's Movie collection. This means,
Action movies Devon's collection
100 85
20 [tex]x[/tex]
If 100 corresponds to 85, then 20 will correspond to a less value than 85. If less more divides,Hence,
[tex]x=\frac{85 \times 20}{100}=17[/tex].
Therefore he has 17 movies that are in Devon's collection.
