Answer 2

To calculate the given ratios, we can use the unitary method, where we consider the ratios and their corresponding values.

1. 2 мин (minutes) от 1 ч (hour) = 1/30 So, 3 сек (seconds) от 1 ч (hour) = ?

Let's find the value in seconds: 1 hour = 60 minutes 1 minute = 60 seconds

Therefore, 2 minutes = 2 * 60 seconds = 120 seconds

Now, we can set up the proportion:

2 minutes / 1 hour = 120 seconds / ? (seconds)

Cross-multiply:

2 * ? = 1 * 120 ? = 120 / 2 ? = 60

So, 3 seconds от 1 hour = 60 seconds.

2. 10 см (centimeters) от 1 м (meter) = ? We know that 1 meter = 100 centimeters.

Now, we can set up the proportion:

10 centimeters / 1 meter = ? (centimeters) / 100 (centimeters)

Cross-multiply:

10 * 100 = 1 * ? ? = 1000

So, 10 centimeters от 1 meter = 1000 centimeters.

3. 5 дм (decimeters) от 1 м (meter) = ? We know that 1 meter = 10 decimeters.

Now, we can set up the proportion:

5 decimeters / 1 meter = ? (decimeters) / 10 (decimeters)

Cross-multiply:

5 * 10 = 1 * ? ? = 50

So, 5 decimeters от 1 meter = 50 decimeters.

4. 10 кг (kilograms) от 1 ц (centner or metric quintal) = ? We know that 1 centner = 100 kilograms.

Now, we can set up the proportion:

10 kilograms / 1 centner = ? (kilograms) / 100 (kilograms)

Cross-multiply:

10 * 100 = 1 * ? ? = 1000

So, 10 kilograms от 1 centner = 1000 kilograms.

5. 1 кг (kilogram) от 1 т (ton) = ? We know that 1 ton = 1000 kilograms.

Now, we can set up the proportion:

1 kilogram / 1 ton = ? (kilograms) / 1000 (kilograms)

Cross-multiply:

1 * 1000 = 1 * ? ? = 1000

So, 1 kilogram от 1 ton = 1000 kilograms.

6. 2 года (years) от 1 века (century) = ? We know that 1 century = 100 years.

Now, we can set up the proportion:

2 years / 1 century = ? (years) / 100 (years)

Cross-multiply:

2 * 100 = 1 * ? ? = 200

So, 2 years от 1 century = 200 years.

7. 3 часа (hours) от 1 суток (day) = ? We know that 1 day = 24 hours.

Now, we can set up the proportion:

3 hours / 1 day = ? (hours) / 24 (hours)

Cross-multiply:

3 * 24 = 1 * ? ? = 72

So, 3 hours от 1 day = 72 hours.

8. 5 мм (millimeters) от 1 см (centimeter) = ? We know that 1 centimeter = 10 millimeters.

Now, we can set up the proportion:

5 millimeters / 1 centimeter = ? (millimeters) / 10 (millimeters)

Cross-multiply:

5 * 10 = 1 * ? ? = 50

So, 5 millimeters от 1 centimeter = 50 millimeters.

9. 3 мм (millimeters) от 1 м (meter) = ? We know that 1 meter = 1000 millimeters.

Now, we can set up the proportion:

3 millimeters / 1 meter = ? (millimeters) / 1000 (millimeters)

Cross-multiply:

3 * 1000 = 1 * ? ? = 3000

So, 3 millimeters от 1 meter = 3000 millimeters.
