If `x%` of `4.260=2.13`, then `x=?`

Options

A. `60`
B. `40`
C. `50`
D. `100`

Answer

To solve the problem, we need to find the value of \( x \) in the equation \( x\% \) of \( 4.260 = 2.13 \).

### Step-by-Step Solution:

1. **Understand the equation**: The phrase "x% of 4.260" can be expressed mathematically as:
\[ \frac{x}{100} \times 4.260 = 2.13 \]

2. **Rearrange the equation**: To isolate \( x \), we can multiply both sides of the equation by 100:
\[ x \times 4.260 = 2.13 \times 100 \]

3. **Calculate the right side**: Now, calculate \( 2.13 \times 100 \):
\[ 2.13 \times 100 = 213 \]
So the equation now looks like:
\[ x \times 4.260 = 213 \]

4. **Solve for \( x \)**: Next, divide both sides by \( 4.260 \) to find \( x \):
\[ x = \frac{213}{4.260} \]

5. **Perform the division**: Now, calculate \( \frac{213}{4.260} \):
\[ x = 50 \]

Thus, the value of \( x \) is \( 50 \).

### Final Answer:
\[ x = 50 \]
