Explanation
The correct answer is 47.000 because 1 hectometer (hm) is equal to 10,000 centimeters (cm). Therefore, to convert 4.7 hm to cm, we multiply 4.7 by 10,000, which equals 47,000.

Explanation
The given answer, 3.8, is the conversion of 3.800 cm to dam. To convert from cm to dam, we divide the value in cm by 10, as there are 10 decimeters in a meter. Therefore, 3.800 cm divided by 10 equals 3.8 dam.

Explanation
The correct answer is 940. To convert kilometers to decameters (dam), we need to move the decimal point one place to the right. Since there is only one digit after the decimal point in 9.4 km, we can simply move it one place to the right to get 94 dam.

Explanation
The question is asking for the conversion of 7 11/20 decimeters to millimeters. Since there are 10 millimeters in 1 decimeter, we can multiply 7 by 10 to get 70 millimeters. Then, we can convert the 11/20 decimeters to millimeters by multiplying it by 10 as well, resulting in 11/2 millimeters or 5.5 millimeters. Adding the two amounts together, we get a total of 70 + 5.5 = 75.5 millimeters. Therefore, the correct answer is 75.500.

Explanation
The correct answer is 8.3 km. To convert from decimeters (dm) to kilometers (km), we need to divide the given value by 10, as there are 10 decimeters in a meter and 1000 meters in a kilometer. Therefore, dividing 83000 dm by 10 gives us 8300 m, and dividing 8300 m by 1000 gives us 8.3 km.

Explanation
The question asks to convert 7 km and 12 hm into meters. Since 1 km is equal to 1000 m and 1 hm is equal to 100 m, we can convert 7 km to 7000 m and 12 hm to 1200 m. Adding these two values together gives us a total of 8200 m, which is equivalent to 8.200 km.

Explanation
To convert 5,3 dm to cm, we need to multiply it by 10 since there are 10 cm in 1 dm. Therefore, 5,3 dm is equal to 53 cm. To convert 290 mm to cm, we need to divide it by 10 since there are 10 mm in 1 cm. Therefore, 290 mm is equal to 29 cm. Subtracting 29 cm from 53 cm gives us 24 cm. Therefore, the correct answer is 24.

Explanation
Bibi Ana memiliki pita sepanjang 225 cm. Pita itu dipotong 1,5 m untuk pengikat rambut anaknya. Jadi, pita yang dipotong memiliki panjang 150 cm (1,5 m = 150 cm). Untuk mengetahui sisa pita, kita dapat mengurangi panjang pita yang dipotong dari panjang pita asli. Jadi, 225 cm - 150 cm = 75 cm. Jadi, sisa pita bibi Ana adalah 75 cm.

Explanation
The difference between the lengths of Anton's and Fuad's ropes can be found by converting the lengths to the same unit of measurement. Since Anton's rope is given in meters and Fuad's rope is given in centimeters, we need to convert Anton's rope length to centimeters. Since 1 meter is equal to 100 centimeters, Anton's rope length is 35 x 100 = 3500 centimeters. The difference between their rope lengths is then 3500 - 3280 = 220 centimeters.

Explanation
Toto has already covered a distance of 6.28 hm, which is equivalent to 62.8 km. Since the total distance of the race is 12.8 km, Toto still has to cover a remaining distance of 12.8 km - 62.8 km = -50 km. However, distance cannot be negative, so it means that Toto has already crossed the finish line and has completed the race. Therefore, the correct answer is 12,172 meters, which is the same as 12.172 km.
