Answer 1

1 km2 = 1000000 m2
1 kg = 0.001 t       1/100
4 kg = 0.004 t       4/100
5 kg = 0.005 t       5/100
6 kg = 0.006 t       6/100
8 kg = 0.008 t       8/100

200 kg = 0.2 t    2/10
300 kg = 0.3 t    3/10
400 kg = 0.4 t    4/10
800 kg = 0.8 t    8/10
900 kg = 0.9 t    9/10

Answer 2

Conversion of 1 km² to m²:

To convert 1 square kilometer (km²) to square meters (m²), we need to multiply the value by the conversion factor.

1 km² is equal to 1,000,000 square meters (m²) because 1 kilometer is equal to 1000 meters, and when we square that, we get 1,000,000.

Therefore, 1 km² is equal to 1,000,000 m².

Expressing weights in metric tons:

To express weights in metric tons, we need to convert the given weights from kilograms (kg) to metric tons (t).

To convert kilograms to metric tons, we divide the weight in kilograms by 1000.

- 3 kg is equal to 0.003 t (3 kg / 1000) - 4 kg is equal to 0.004 t (4 kg / 1000) - 5 kg is equal to 0.005 t (5 kg / 1000) - 6 kg is equal to 0.006 t (6 kg / 1000) - 8 kg is equal to 0.008 t (8 kg / 1000)

Therefore, the weights expressed in metric tons are: 3 kg = 0.003 t, 4 kg = 0.004 t, 5 kg = 0.005 t, 6 kg = 0.006 t, and 8 kg = 0.008 t.

Expressing weights in metric tons as fractions:

To express weights in metric tons as fractions, we can write them as a fraction with the numerator being the weight in kilograms and the denominator being 1000.

- 3 kg can be written as 3/1000 t - 4 kg can be written as 4/1000 t - 5 kg can be written as 5/1000 t - 6 kg can be written as 6/1000 t - 8 kg can be written as 8/1000 t

Therefore, the weights expressed in metric tons as fractions are: 3 kg = 3/1000 t, 4 kg = 4/1000 t, 5 kg = 5/1000 t, 6 kg = 6/1000 t, and 8 kg = 8/1000 t.

Conversion of weights to metric tons using different fractions:

To express weights in metric tons using different fractions, we can choose different denominators for the fractions.

For example, let's convert the weights 200 kg, 300 kg, 400 kg, 800 kg, and 900 kg to metric tons using three different fractions.

Using a denominator of 100: - 200 kg can be written as 2/10 t - 300 kg can be written as 3/10 t - 400 kg can be written as 4/10 t - 800 kg can be written as 8/10 t - 900 kg can be written as 9/10 t

Using a denominator of 1000: - 200 kg can be written as 2/100 t - 300 kg can be written as 3/100 t - 400 kg can be written as 4/100 t - 800 kg can be written as 8/100 t - 900 kg can be written as 9/100 t

Using a denominator of 10000: - 200 kg can be written as 2/1000 t - 300 kg can be written as 3/1000 t - 400 kg can be written as 4/1000 t - 800 kg can be written as 8/1000 t - 900 kg can be written as 9/1000 t

Therefore, the weights expressed in metric tons using different fractions are as follows: - Using a denominator of 100: 200 kg = 2/10 t, 300 kg = 3/10 t, 400 kg = 4/10 t, 800 kg = 8/10 t, and 900 kg = 9/10 t. - Using a denominator of 1000: 200 kg = 2/100 t, 300 kg = 3/100 t, 400 kg = 4/100 t, 800 kg = 8/100 t, and 900 kg = 9/100 t. - Using a denominator of 10000: 200 kg = 2/1000 t, 300 kg = 3/1000 t, 400 kg = 4/1000 t, 800 kg = 8/1000 t, and 900 kg = 9/1000 t.

Calculation of the time Anne was away from home:

To calculate the time Anne was away from home, we need to subtract the time she left for school from the time she returned.

Anne left for school at 8:35 AM and returned at 2:15 PM. To calculate the duration, we subtract the start time from the end time.

- 2:15 PM can be converted to 14:15 in 24-hour format. - 8:35 AM can be converted to 8:35 in 24-hour format.

To subtract the times, we perform the following calculation:

14:15 - 8:35 = 5 hours and 40 minutes.

Therefore, Anne was away from home for 5 hours and 40 minutes.
