13,7/4=9t/3,6

To solve the equation \( \frac{13.7}{4} = \frac{9t}{3.6} \), we can follow these steps:

1. Start by simplifying both sides of the equation.

   Calculate \( \frac{13.7}{4} \): \[ \frac{13.7}{4} = 3.425 \]

   Now the equation looks like this: \[ 3.425 = \frac{9t}{3.6} \]

2. Multiply both sides by \( 3.6 \) to eliminate the fraction on the right side: \[ 3.425 \times 3.6 = 9t \]

3. Calculate \( 3.425 \times 3.6 \): \[ 3.425 \times 3.6 = 12.306 \]

   So, we have: \[ 12.306 = 9t \]

4. Now, divide both sides by 9 to solve for \( t \): \[ t = \frac{12.306}{9} \]

5. Calculate \( \frac{12.306}{9} \): \[ t \approx 1.367 \]

Thus, the solution is: \[ t \approx 1.367 \]
