Question

convert 9 deci metre 8 km into hectometer

Answer 1

Hey friend...!!!

8 km 9 dm =====> hectometer

So, 1 km = 10 hectometer
8 km = 8 × 10 hectometer
8 km = 80 hectometer
And,
1 dm = 1/1000 hectometer
9 dm = 9/1000 hectometer
9 dm = 0.009 hectometer

So, overall = 80 + 0.009 hectometer
= 80.009 hectometer

Hope it helps...!! §§§
