Final answer:
To find a number that is a certain percentage of another number, we can use proportions.
Step-by-step explanation:
To find a number that is a certain percentage of another number, we can use proportions. In this case, we want to find what number is 25% of 64.
We can set up a proportion:
25/100 = x/64
To solve the proportion, we can cross multiply:
25 * 64 = 100 * x
Simplifying, we get:
1600 = 100x
Dividing both sides by 100, we find that x is 16.
So, the number that is 25% of 64 is 16.
