Question

Express 35 mm in cm and km m

Answer 1

Given condition= 35cm..

Converting into cm..(1cm=10mm)...
so 35 mm=35/100=0.35cm...

Converting into km...(1km=1000000mm)
so... 35mm= 35/10000000=0.0000035mm..

Converting into metre...(1m=1000mm)
so 35 mm=35/1000=0.035mm

Answer 2

The correct answers are i) 35 mm = 3.5 cm, ii) 35 mm  = 0.000035 km, and iii)35 mm  = 0.035 m.

Given:

Convert 35 mm into cm, km, and m.

To Find:

35 mm = ____ cm

35 mm = ____ km

35 mm = ____m

Solution:

i) Convert 35 mm into cm.

We know that 1 cm = 10 mm.

1 mm   = 1/10 cm

So to find 35 mm in cm, we will multiply 35 onto both sides.

⇒ 35 mm = 35/10 cm

∴ 35 mm = 3.5 cm

ii). Convert 35 mm into Km.

We know that

1 Km = 1000 m

1 m = 100 cm

1 cm = 10 mm

So 1 Km in terms of mm is calculated as

⇒ 1 Km = 1000 m = 1000 x 100 cm = 1000 x 100 x 10 mm = 10,00,000 mm

Or we can write

1 mm = 1/(10,00,000) Km

So to find 35 mm in Km, we will multiply 35 onto both sides of the above equation.

⇒ 35 mm = 35/(10,00,000) Km

∴ 35 mm = 0.000035 Km

iii). Convert 35 mm into m.

We know that

1 m = 100 cm

and 1 cm = 10 mm.

So 1 m in terms of mm is calculated as:

1 m = 100 cm =  100 x 10 mm = 1000 mm

Or we can write

1 mm = 1/1000 m

So to find 35 mm in m, we will multiply 35 onto both sides of the above equation.

⇒ 35 mm = 35/1000 m

∴ 35 mm = 0.035 m

∴ The correct answers are i) 35 mm = 3.5 cm, ii) 35 mm  = 0.000035 km, and iii)35 mm  = 0.035 m.
