51 % of a whole number Is 714. Find 25% of that number is

Options

A. 350
B. 450
C. 550
D. 250

Answer

To solve the problem step by step, we will first determine the whole number based on the information given, and then we will calculate 25% of that number.

### Step 1: Set up the equation
We know that 51% of a whole number (let's call it \( x \)) is equal to 714. We can express this mathematically as:
\[ 0.51x = 714 \]

### Step 2: Solve for \( x \)
To find \( x \), we need to isolate it. We can do this by dividing both sides of the equation by 0.51:
\[ x = \frac{714}{0.51} \]

### Step 3: Calculate \( x \)
Now, we will perform the division:
\[ x = \frac{714}{0.51} = 1400 \]

### Step 4: Find 25% of \( x \)
Now that we have found \( x \) (the whole number), we need to calculate 25% of it:
\[ 25\% \text{ of } x = 0.25 \times 1400 \]

### Step 5: Calculate 25% of \( x \)
Now, we will perform the multiplication:
\[ 0.25 \times 1400 = 350 \]

### Final Answer
Thus, 25% of the number is:
\[ \boxed{350} \]
