Question

(a) Convert 0.43 dekameters (dam) to meters (m).Conversion facts for length1000 millimeters (mm) = 1 meter (m)m(b) Convert 2.1 meters (m) to hectometers (hm).Ihm100 centimeters (cm) - 1 meter (m)10 decimeters (dm) =1 meter (m)1 dekameter (dam)= 10 meters (m)X 5?1 hectometer (hm) = 100 meters (m)1 kilometer (km) 1000 meters (m)

Answer 1

To solve this question we must apply rule of three a couple of times.

1 dam ----- 10 m

0.43 dam ----- y

Solving for y:

1 dam . y = 0.43 dam . 10 m

y = 0.43 dam . 10 m / 1 dam

y = 4.3 m (answer)

Now let's calculate the second question.

1 hm ------ 100 m

z ------------ 2.1 m

Solving for z:

z . 100 m = 1 hm . 2.1 m

z = 1 hm . 2.1 m / 100 m

z = 0.021 hm (answer)
