21 - (3 x 4)
3 x 4 is 12, so it becomes 21 - 12.
21 - 12 = 9
So to solve this problem, we can either do guess and check, or solve an equation.
Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.
So, to begin, let's define our unknown.
We can represent the number as "n"
So, 6 percent of "n" is equal to 270
To find a "percent" of a number, you need to multiply the number by the percentage.
So, 6 percent as a decimal is .06
This is because a percent is a fraction divided by 100 (6/100)

The number is 4,500
Answer: a). 1/8
Step-by-step explanation:
