Answer 1

Ответ:

9408:98×12786-2136:24×5007=781 833

(679801-597888)×103-6999999=1 437 040

21саг15мин+6саг49мин-1день=1275+409=1684-1440=244(4часа 06 минут)

Answer 2

Let's break down each of the calculations step by step:

1. 9408 divided by 98: 9408 ÷ 98 = 96

2. 12786 divided by 24: 12786 ÷ 24 = 532.75

3. 96 multiplied by 532.75: 96 × 532.75 = 51,102

4. 679801 minus 597888: 679801 - 597888 = 81913

5. 81913 multiplied by 103: 81913 × 103 = 8,433,739

6. 6999999: 6999999

Now, let's calculate the time:

1. 21 hours and 15 minutes plus 6 hours and 49 minutes: 21:15 + 6:49 = 28:64

Since there are 60 minutes in an hour, you need to convert the extra minutes into hours:

2. 28 hours + (64 minutes ÷ 60) hours = 28 hours + 1.0667 hours = 29.0667 hours

Now, let's calculate the weight:

1. 90 tons minus 10 tons 9 centners 47 kilograms: 90t - 10t 9c 47kg

To subtract, first convert centners and kilograms to tons: 1 centner = 0.1 ton 1 kilogram = 0.001 ton

So, 10 centners 9 kilograms is equal to 10.009 tons:

10c 9kg = 10 × 0.1t + 9 × 0.001t = 1t + 0.009t = 1.009t

Now, subtract the weights:

90t - 1.009t - 47kg = (90 - 1.009)t - 47kg ≈ 88.991t - 47kg

So, the result is approximately 88.991 tons minus 47 kilograms.

Now, you have all the results:

1. 9408 ÷ 98 = 96
2. 12786 ÷ 24 = 532.75
3. 96 × 532.75 = 51,102
4. 679801 - 597888 = 81913
5. 81913 × 103 = 8,433,739
6. 6999999
7. 29.0667 hours
8. 88.991 tons - 47 kilograms
