# Write a percent equation that can be used to solve the following problem: 820 is 20% of what number?

A. n = 0.2 x 820

B. 820 = 0.2 × n

C. 0.2 = n × 820

D. none of these

## A. n = 164

B. n = 4100

C. n = 0.00024

Which is the only logical answer?

## is it b?

## D. none of these

Because the question is asking for "820 is 20% of what number," we need to set up an equation where the unknown number is being multiplied by 20% (0.2). The equation should be:

n × 0.2 = 820

## To solve the problem "820 is 20% of what number?", we can set up a percent equation. A percent equation compares a part to a whole using a proportion.

Let's designate the unknown number as 'n'. We are given that 820 is 20% of this unknown number. The equation should express this relationship.

The equation is: 820 = 0.2 × n

Therefore, the correct answer is B. 820 = 0.2 × n.

## Yes, B.

820 is 20% of 4,100
