43м 7дм +8м 3см+ 62дм 7см = 35км 20м -915м -2км 5м = 5дм 7см +1см 8мм + 7м 12мм = 8кг 300г+ 7кг 50г+ 15кг 4 г = 2мин 40с + 5 мин 48 с + 3 мин 32 с пожалуйста по действиям и преводить

Answer 1

35км 20м-915м-2км 5м=32км100м
43м 7дм + 8м 3см +62дм 7см=58 м
5дм 7см+1см 8мм+7м 12мм=76 дм
8кг 300г+7кг 50г+15кг 4г=30.35400 кг

Answer 2

Calculation of Lengths and Weights

To solve the given addition problems, let's start by converting all the measurements to a consistent unit before performing the addition.

1. Addition of Lengths: - 43m 7dm + 8m 3cm + 62dm 7cm - Converting all measurements to centimeters: - 43m 7dm = (43 * 100)cm + (7 * 10)cm = 4300cm + 70cm = 4370cm - 8m 3cm = (8 * 100)cm + 3cm = 800cm + 3cm = 803cm - 62dm 7cm = (62 * 10)cm + 7cm = 620cm + 7cm = 627cm - Adding the converted measurements: 4370cm + 803cm + 627cm = 5799cm

2. Subtraction of Lengths: - 35km 20m - 915m - 2km 5m - Converting all measurements to meters: - 35km = 35 * 1000m = 35000m - 2km = 2 * 1000m = 2000m - 35km 20m = 35000m + 20m = 35020m - 2km 5m = 2000m + 5m = 2005m - Performing the subtraction: 35020m - 915m - 2005m = 32000m

3. Addition of Lengths (in smaller units): - 5dm 7cm + 1cm 8mm + 7m 12mm - Converting all measurements to millimeters: - 5dm 7cm = (5 * 10)cm + 7cm = 50mm + 7mm = 57mm - 1cm 8mm = 1cm + 8mm = 18mm - 7m 12mm = (7 * 1000)mm + 12mm = 7000mm + 12mm = 7012mm - Adding the converted measurements: 57mm + 18mm + 7012mm = 7087mm

4. Addition of Weights: - 8kg 300g + 7kg 50g + 15kg 4g - Adding the weights directly: 8kg 300g + 7kg 50g + 15kg 4g = 30kg 354g

5. Addition of Time Durations: - 2min 40s + 5min 48s + 3min 32s - Adding the time durations: 2min 40s + 5min 48s + 3min 32s = 11min 60s = 12min

Results:

1. 43m 7dm + 8m 3cm + 62dm 7cm = 5799cm 2. 35km 20m - 915m - 2km 5m = 32000m 3. 5dm 7cm + 1cm 8mm + 7m 12mm = 7087mm 4. 8kg 300g + 7kg 50g + 15kg 4g = 30kg 354g 5. 2min 40s + 5min 48s + 3min 32s = 12min
