Replace `'square'` in each of the following by the correct number :
`square/7=6""3/7`

Answer

To solve the equation \( \frac{\text{square}}{7} = 6 \frac{3}{7} \), we will follow these steps:

### Step 1: Convert the mixed fraction to an improper fraction
The mixed fraction \( 6 \frac{3}{7} \) can be converted into an improper fraction.

To do this, we multiply the whole number (6) by the denominator (7) and then add the numerator (3):
\[ 6 \times 7 + 3 = 42 + 3 = 45 \]
So, \( 6 \frac{3}{7} = \frac{45}{7} \).

### Step 2: Set up the equation
Now, we can rewrite the equation:
\[ \frac{\text{square}}{7} = \frac{45}{7} \]

### Step 3: Eliminate the denominator
To eliminate the denominator, we can multiply both sides of the equation by 7:
\[ \text{square} = 45 \]

### Step 4: Conclusion
Thus, the value of 'square' is:
\[ \text{square} = 45 \]

### Final Answer
The correct number to replace 'square' is **45**.
