There are 20 decimeters (dm) in 2 meters (m) because 1 meter is equal to 10 decimeters. Therefore, to convert 2 meters to decimeters, you multiply 2 by 10, resulting in 20 dm.
To determine how much cloth is wasted when cutting 18 dm from a 2m by 2m piece, we first convert the dimensions to the same unit. A 2m by 2m piece of cloth is equivalent to 200 dm by 200 dm, giving a total area of 40,000 dm². If 18 dm is cut from this piece, the area of the cut is 18 dm². Therefore, the waste can be calculated by subtracting the area cut from the total area, which would be 40,000 dm² - 18 dm² = 39,982 dm² of cloth remains, with only the 18 dm² cut being wasted.
8.4 dm
15 dm equals 150cm
500 mm = 5 dm
1 m = 10 dm, so 0.76 m = 7.6 dm
decimeter or dm=10 meters. 20 dm equals 200 meters * * * * * Correction. A decimetre is a tenth of a metre so 20 dm = 2m
8.4 dm
15 dm equals 150cm
100 mm = 1 dm
1 dm is equal to 100 mm (as 1 dm = 10 cm 1 cm = 10 mm)
500 mm = 5 dm
70
36 cm (centimetres) = 3.6 dm (decimetres)
2 m
1 m = 10 dm, so 0.76 m = 7.6 dm
