Answer:
42
Explanation:
If Naomi has 168 apps, then 100% is equal to 168 (since that's all her apps)
If 25% of these apps are games, then 25% is equal to x
If we multiply the number of total apps by the percentage of games, we'll find the total number of game apps
First change the percentage into a decimal:
25% = 0.25
Then multiply:
168 * 0.25 = x
Simplify:
x = 42
Another way you can do this is by realizing that 0.25 is equal to 1/4. If 168 is multiplied by 1/4, then that means the resulting equation is:
168/4 = x
x results in the same answer as the previous way:
x = 42
