Question

80% of a number is divided by 2. Write it as a mathematical expression.
0.4x
0.8x
40x
8x

Answer 1

To express "80% of a number is divided by 2," we can break it down into steps:

1. Let the number be represented by \( x \).
2. Calculate 80% of the number: \( 0.8x \).
3. Now, we need to divide that result by 2:

\[
\frac{0.8x}{2}
\]

This can also be simplified to:

\[
0.4x
\]

So, the correct mathematical expression is \( 0.4x \).
