Q: If 30% of a number is 150, what is the number?
Solution:
Let the number be x. Then, 0.3x = 150. Therefore, x = 150 / 0.3 = 500.
Steps: 7
Show Steps
Step 1: Understand that 30% means 30 out of 100, or 0.3 in decimal form.
Step 2: Let the unknown number be represented by 'x'.
Step 3: Write the equation for 30% of 'x': 0.3 * x = 150.
Step 4: To find 'x', we need to isolate it. We can do this by dividing both sides of the equation by 0.3.
Step 5: Perform the division: x = 150 / 0.3.
Step 6: Calculate the result: 150 divided by 0.3 equals 500.
Step 7: Therefore, the number is 500.
