Take a number x, and multiply it with 5. Take the cube of the resulting number. What is the ratio of this number to the cube of the original number?
Answer:
125:1
- If we multiply the number x with 5, the resulting number is 5x.
- The cube of the resulting number 5x = (5x)3
= 125x3 - The original number is x.
Cube of the original number = x3. - The ratio of the new number to the original number =
New number Original number
=125x3 x3
=125 1 - Therefore, the ratio of the new number to the cube of the original number is 125:1.
