Answer:
20.
Explanation:
Hey! Let's help ya with your question here!
So, what we know is that he has 24 apps in total on his phone and that the ratio of educational apps to gaming apps is 5:1 and we need to find out how many educational apps there are.
Now the ratio, 5:1, is essentially saying for every 5 educational apps Lance has, he has 1 gaming app. Meaning he'll have 6 apps in total (5 educational, 1 gaming). But he has 24 apps in total, so we just simply divide the total apps on his phone (24 apps) by the 6 apps of the ratio we just figured out and we get 4!
This is important as we know that this ratio is applied 4 times. Now we can go through each ratio and add it to the original ratio 4 times! So that would be:
Therefore, he has 20 educational apps on his phone!
Another way, we can do this is to take the ratio 5:1 and since we need to apply the ratio 4 times to get a total of 24 apps, we can multiply each number in the ratio by 4, so that would be:
Here it is saying his ratio is 20 educational apps to 4 gaming apps.
