Q
Q: If 20% of a number is 50, what is the number?
Solution:
Let the number be x. Then, 0.2x = 50. Therefore, x = 50 / 0.2 = 250.
Steps: 7
Show Steps
Step 1: Understand that 20% means 20 out of 100, which can be written as a decimal: 20% = 0.2.
Step 2: Let the unknown number be represented by 'x'.
Step 3: Write the equation for 20% of 'x': 0.2 * x = 50.
Step 4: To find 'x', we need to isolate it. We can do this by dividing both sides of the equation by 0.2.
Step 5: Perform the division: x = 50 / 0.2.
Step 6: Calculate 50 divided by 0.2, which equals 250.
Step 7: Conclude that the number is 250.
