Question

2400mm+120cm+ 50m+4 km
​

Answer 1

Step-by-step explanation:

2400mm+120cm+50m+4km

Before sum we have to convert in the same units

we know that,

1cm=10mm

2400mm=2400/10=240cm

1m=100cm

50m=50*100=5000cm

1km=100000cm

4km=400000cm

now,

the sum of

240+120+5000+400000

405360cm

if you write in metres

405360/100

4053.60metres

if you write in kilometres

405360/100000

4.05360kilometres
