Answer 2

As we know that,

• To convert mm to m divide the length value by 1000.
• To convert mm to m divide the length value by 1000.To convert mm to cm divide the length value by 10.

a. 1200 mm

for m conversation,

1200 mm

$= \frac{1200}{1000}$

$= 1.200 \: m$

The value of zero after the point is negligible.

So, 1200 mm = 1.2 m

For cm conversation,

1200 mm

$= \frac{1200}{10}$

$= 120.0 \: cm$

The value of zero after the point is negligible.

So, 1200 mm = 120 cm

By converting we get,

1200 mm is equal to 1.2 m and 120 cm

b. 250 mm

for m conversation,

250 mm

$= \frac{250}{1000}$

$= 0.250 \: m$

The value of zero after the point is negligible.

So, 250 mm = 0.25 m

For cm conversation,

250 mm

$= \frac{250}{10}$

$=25.0 \: cm$

The value of zero after the point is negligible.

So, 250 mm = 25 cm

By converting we get,

250 mm is equal to 0.25 m and 25 cm

d. 8500 mm

for m conversation,

8500 mm

$= \frac{8500}{1000}$

$= 8.500 \: m$

The value of zero after the point is negligible.

So, 8500 mm = 8.5 m

For cm conversation,

8500 mm

$= \frac{8500}{10}$

$=850.0 \: cm$

The value of zero after the point is negligible.

So, 8500 mm = 850 cm

By converting we get,

8500 mm is equal to 8.5 m and 850 cm

c. 7500 mm

for m conversation,

7500 mm

$= \frac{7500}{1000}$

$= 7.500 \: m$

The value of zero after the point is negligible.

So, 7500 mm = 7.5 m

For cm conversation,

7500 mm

$= \frac{7500}{10}$

$=750.0 \: cm$

The value of zero after the point is negligible.

So, 7500 mm = 750 cm

By converting we get,

7500 mm is equal to 7.5 m and 750 cm.
