312÷x=8

To solve the equation \( 312 \div x = 8 \), you can follow these steps:

1. Rewrite the equation: \[ \frac{312}{x} = 8 \]

2. Multiply both sides by \( x \) to eliminate the denominator: \[ 312 = 8x \]

3. Now, solve for \( x \) by dividing both sides by 8: \[ x = \frac{312}{8} \]

4. Perform the division: \[ x = 39 \]

So, the solution is \( x = 39 \).
