34/40*60/1

To calculate \( \frac{34}{40} \times \frac{60}{1} \):

1. Simplify \( \frac{34}{40} \):

   • The greatest common divisor (GCD) of 34 and 40 is 2.
   • So, \( \frac{34 \div 2}{40 \div 2} = \frac{17}{20} \).

2. Now multiply \( \frac{17}{20} \) by \( \frac{60}{1} \):

   • \( \frac{17}{20} \times 60 = \frac{17 \times 60}{20} \).

3. Calculate \( 17 \times 60 = 1020 \).

4. Now divide \( 1020 \) by \( 20 \):

   • \( \frac{1020}{20} = 51 \).

Therefore, \( \frac{34}{40} \times \frac{60}{1} = 51 \).
