2)5700+742-108=6442-108=6334

Answer 2

Let's break down the calculations step by step.

1. 7m 6cm - 3m 8dm + 6cm 7mm: To perform this calculation, we need to convert all units to a common unit (centimeters) and then add them together.

• 7m 6cm = 706cm
• 3m 8dm = 308cm (1 decimeter = 10 centimeters)
• 6cm 7mm = 67mm (1 millimeter = 0.1 centimeters)

Now, we can add them up:

706cm - 308cm + 67mm = 706cm - 308cm + 6.7cm = 398.7cm

So, 7m 6cm - 3m 8dm + 6cm 7mm = 398.7cm.

2. 5t 7c + 742kg - 1c 8kg: To perform this calculation, we need to convert all units to a common unit (centners) and then add them together.

• 5t 7c = 507c (1 ton = 10 centners)
• 742kg = 7.42c (1 ton = 100 centners, 1 centner = 100 kg)
• 1c 8kg = 1.08c (1 centner = 100 kg)

Now, we can add them up:

507c + 7.42c - 1.08c = 513.34c

So, 5t 7c + 742kg - 1c 8kg = 513.34 centners.

Please note that centners (c) are a unit of mass equal to 100 kilograms. If you meant to use different units or if there's any specific context, let me know so I can adjust the calculations accordingly.
