Complete the following equivalent fractions:
`48/(72)=square/(9)`

Answer

To solve the problem of finding the equivalent fraction for \( \frac{48}{72} = \frac{x}{9} \), we can follow these steps:

### Step 1: Understand the relationship between the fractions
We know that for two fractions to be equivalent, the cross products must be equal. This means:
\[ 48 \times 9 = 72 \times x \]

### Step 2: Calculate the left side of the equation
Now, we can calculate \( 48 \times 9 \):
\[ 48 \times 9 = 432 \]

### Step 3: Set up the equation
Now we can set up the equation:
\[ 432 = 72 \times x \]

### Step 4: Solve for \( x \)
To find \( x \), we need to divide both sides of the equation by 72:
\[ x = \frac{432}{72} \]

### Step 5: Calculate \( x \)
Now we can perform the division:
\[ x = 6 \]

### Step 6: Write the final answer
Thus, the equivalent fraction is:
\[ \frac{48}{72} = \frac{6}{9} \]
So, the blank should be filled with 6.
