Answer:
37.5
Explanation:
If 80% of a number is 30, then we can use the proportion method to find 100% of the number. Let x be the number we are looking for. Then we have:
80/100 = 30/x
Multiplying both sides by x, we get:
80x/100 = 30
Simplifying, we get:
4x/5 = 30
Multiplying both sides by 5/4, we get:
x = (5/4) × 30 = 37.5
Therefore, 100% of the number is 37.5
