Answer 1

To represent the phrase 'what number' in the equation '300% of what number is 180', you can use a variable, such as x. The number represented by 'what number' is 60.

Step-by-step explanation:

To represent the phrase 'what number' in the equation '300% of what number is 180', we can use a variable, such as x.

Let's set up the equation:

300% of x = 180

To solve the equation, we need to convert the percent to a decimal. Divide 300 by 100 to get 3. 3 times x equals 180.

To isolate x, divide both sides of the equation by 3:

x = 180 ÷ 3

x = 60

Therefore, the number represented by 'what number' is 60.
