Answer 2

Let's solve the expression step by step:

1. Convert everything to the same unit, centimeters (cm):

   • 6m 20cm = (6 * 100cm) + 20cm = 620cm
   • 1m 60cm = (1 * 100cm) + 60cm = 160cm

2. Now, we can simplify the expression: 620cm : 31 + 30cm × 4 - 160cm

3. Perform multiplication and division first: 620cm : 31 = 20cm (approximately) 30cm × 4 = 120cm

4. Now, the expression becomes: 20cm + 120cm - 160cm

5. Finally, add and subtract: 20cm + 120cm = 140cm 140cm - 160cm = -20cm

The final result is -20cm.
