54/45*9*15

To simplify the expression \( \frac{54}{45} \times 9 \times 15 \), we can follow these steps:

1. Simplify \( \frac{54}{45} \):

   • The greatest common divisor (GCD) of 54 and 45 is 9.
   • \( \frac{54 \div 9}{45 \div 9} = \frac{6}{5} \)

2. Now substitute back into the expression: \[ \frac{6}{5} \times 9 \times 15 \]

3. Multiply \( \frac{6}{5} \) by 9: \[ \frac{6 \times 9}{5} = \frac{54}{5} \]

4. Multiply \( \frac{54}{5} \) by 15: \[ \frac{54 \times 15}{5} = \frac{810}{5} = 162 \]

Thus, \( \frac{54}{45} \times 9 \times 15 = 162 \).
