Question

One-eighth of a number is -4,200.

What is the number?

-42,000
-37,800
-33,600
-42,800

Answer 1

Let the number be \( x \). According to the problem, one-eighth of the number is -4,200. This can be expressed mathematically as:

\[
\frac{x}{8} = -4200
\]

To find \( x \), we can multiply both sides of the equation by 8:

\[
x = -4200 \times 8
\]

Calculating the right-hand side:

\[
x = -33600
\]

Now, let's compare this result to the options given:

-42,000
-37,800
-33,600
-42,800

The correct answer is:

\[
\boxed{-33,600}
\]
