Answer:

When we subtract 243km 8hm 5dm from 500km 4hm 3dam we get -256.63 km .

Step-by-step explanation:

Given -

Subtract 243km 8hm 5dm from 500km 4hm 3dam ​

To find -

The value of subtraction

Solution -

dm = Decimeter

dam = Decameter

hm = Hectometer

km = kilometer

For subtraction all the values should have same units.

For that convert all the values to km .

To convert dm into km divide the length value by 10000.

∴ $5 \: dm = 0.0005 \: km$

To convert dam into km divide the length value by 100 .

∴ $3 \: dam = 3 \div 100= 0.03\:km$

To convert hm to km divide the length value by 10 .

∴ $8\:hm =8\div 10= 0.8 \:km$

$4\:hm =4\div 10= 0.4 \:km$

243km 8hm 5dm = $243 + 0.8+0.0005 = 243.8 \:km$

500km 4hm 3dam ​= $500+0.4+0.03 = 500.43 \: km$

Now substract,

243km 8hm 5dm - 500km 4hm 3dam

= $243.8-500.43$

= $-256.63$ km

∴ When we subtract 243km 8hm 5dm from 500km 4hm 3dam we get -256.63 km .
