Cross multiply. What do you get?
In the statement "150 is 75% of what number?", we can identify the following elements:
Rate: 75%
Base: unknown number (represented by "what number?")
Amount: 150
To identify the rate, base, and amount in the given statement, let's break down the information:
Statement: 150 is 75% of what number?
In this case:
- The rate is 75% (expressed as a percentage).
- The base is the unknown number we are trying to find.
- The amount is 150.
To solve the exercise, we can set up an equation using the formula for finding the percentage of a number:
Amount = Rate * Base
In this case, the amount is 150, the rate is 75% (which is equivalent to 0.75 when expressed as a decimal), and the base is the unknown number.
So, the equation becomes:
150 = 0.75 * Base
To solve for the base (unknown number), we can divide both sides of the equation by 0.75:
150 / 0.75 = Base
This simplifies to:
200 = Base
Therefore, 150 is 75% of the number 200.
