UpStudy AI · Accepted Answer

To solve the equation:

$$
9 \quad \square \times 7 = 28
$$

we need to determine what should replace the square ($$\square$$) to make the equation true.

### Step-by-Step Solution:

1. **Interpret the Equation:**
   
   The equation can be read as:
   
   $$
   9 \times (\square) \times 7 = 28
   $$
   
   This implies:
   
   $$
   9 \times \square \times 7 = 28
   $$

2. **Isolate the Square ($$\square$$):**
   
   To find the value of $$\square$$, divide both sides of the equation by $$9 \times 7$$:
   
   $$
   \square = \frac{28}{9 \times 7} = \frac{28}{63}
   $$
   
3. **Simplify the Fraction:**
   
   $$
   \frac{28}{63} = \frac{4}{9}
   $$
   
4. **Verify the Solution:**
   
   Substitute $$\square$$ with $$\frac{4}{9}$$ in the original equation:
   
   $$
   9 \times \frac{4}{9} \times 7 = 4 \times 7 = 28
   $$
   
   The equation holds true.

### Conclusion:

The square ($$\square$$) should be replaced with the fraction $$\frac{4}{9}$$.

$$
9 \times \frac{4}{9} \times 7 = 28
$$

**Answer:** The square must be replaced with the fraction $$\frac{4}{9}$$.
The square should be replaced with $$\frac{4}{9}$$.

\( 9 \quad \square \times 7 = 28 \)
