The product of two numbers is 2.0016. If one of them is 0.72, find the other number.

Options

A. 2.078
B. 2.0078
C. 2.78
D. 0.278

Answer

To find the other number when the product of two numbers is given, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: We know that the product of two numbers is 2.0016, and one of the numbers is 0.72. We need to find the other number.

2. **Set Up the Equation**: Let’s denote the other number as \( x \). According to the problem, we can write the equation:
\[ 0.72 \times x = 2.0016 \]

3. **Isolate \( x \)**: To find \( x \), we need to divide both sides of the equation by 0.72:
\[ x = \frac{2.0016}{0.72} \]

4. **Perform the Division**: Now, we will calculate \( \frac{2.0016}{0.72} \). To make the division easier, we can eliminate the decimals by multiplying both the numerator and the denominator by 100:
\[ x = \frac{2.0016 \times 100}{0.72 \times 100} = \frac{200.16}{72} \]

5. **Calculate the Division**: Now, we perform the division:
\[ x = \frac{200.16}{72} \approx 2.78 \]

6. **Conclusion**: Therefore, the other number is:
\[ x \approx 2.78 \]

### Final Answer:
The other number is **2.78**.
