Question

Дам 50 баллов кто поможет решить: определите с точностью до сотых долей процента сколько процентов составляет: 27 м от 340 м 998 м от 4,7 км 12 г от 3 га 678 мт от 2,3 гт 6774 мт от 1,3 гт 7890 га от 1 км 2

Answer 1

27:340*100=7.94%
998:4700*100=21.23%
12:3*100=400%
678:2300*100=29.48%
6774:1300*100=521.08%
78.9:1*100=7890%

Answer 2

Calculating Percentages

To calculate the percentage, we can use the formula:

Percentage = (Part/Whole) * 100

Let's calculate the percentages for the given values:

1. 27 m out of 340 m: - Percentage = (27/340) * 100 - Percentage = 7.94%

2. 998 m out of 4.7 km (4700 m): - Percentage = (998/4700) * 100 - Percentage = 21.23%

3. 12 g out of 3 kg (3000 g): - Percentage = (12/3000) * 100 - Percentage = 0.4%

4. 678 mt out of 2.3 gt (2300 mt): - Percentage = (678/2300) * 100 - Percentage = 29.48%

5. 6774 mt out of 1.3 gt (1300 mt): - Percentage = (6774/1300) * 100 - Percentage = 521.08% (This seems to be an error as the percentage cannot exceed 100%)

6. 7890 ga out of 1 km^2 (1,000,000 m^2): - Percentage = (7890/1000000) * 100 - Percentage = 0.79%

It seems there might be an error in the calculation for the fifth value, as the percentage exceeds 100%. I will recheck the calculation for the fifth value.
