Question

Match the quantities that are equal.

• A. 0.892 kg
• B. 8.92 m
• C. 4200 g
• D. 420 cm

Answer 1

You know,
$1m=100cm$

and conversely,

$1cm=1÷100m=0.01m$

For the conversion between centimetres (cm) and metres (m), you have the following relation:


So, $892cm=(892÷100)m=8.92m$

and,

$4.2m=(4.2\times 100)cm=420cm$.

Again, you know,
$1kg=1000gm$

and conversely,

$1gm=1÷1000kg=0.001kg$.

So, for grams (g) and kilograms (kg),


So, $892g=(892÷1000)kg=0.892kg$

and,

$4.2kg=(4.2\times 1000)g=420g$.

So, the correct way to match the values are:

892 g	0.892 kg
892 cm	8.92 m
4.2 kg	4200 g
4.2 m	420 cm
