Answer 2

Answer:

b)2000cm

c)22000cm

d)24m

To convert

cm to mm

m to cm

m to cm

cm to m

Solution

As per question we need to convert quantities in mm cm and m hence

As we know that

$1cm = 10mm$

$1m = 100cm$

then

a) 150cm need to convert in mm

hence

$150cm = 10 \times 150mm \\ = 1500mm$

b)20m need to convert in cm

$20m = 100 \times 20 \\ = 2000cm$

c)220m to cm

$220m = 220 \times 100 \\ = 22000cm$

d)2400cm to m

$2400cm = \frac{2400}{100} \\ = 24m$
