Answer 1

Answer:

b. 1000m/1km

c. 1m/100cm

g. 1m/1000mm

Explanation:

To solve this you just have to keep in mind the conversion tables that meters have and that is given by the latin pre-fixes that are involved in their names:

1 meter.

1 kilo-meter, kilo means a thousand, so a kilo-meter would be a thousand meters.

1 mili-meter, mili means diveded by thousand, that means that there are a thousand mili-meters in a meter.

1 centi-meter, centi means divided by a hundred, so there are a hundred centi-meters in a meter.

That is why those are the correct options.

Answer 2

The standard fractions which represent correct conversion factors (ratios) are: 1000m/1km, 1m/100cm, 1m/1000mm.

This goes to say that:

1000m = 1km

1m = 100cm

1m = 1000mm.

Recall

10mm = 1cm

10cm = 1dm

10dm = 1m

1000m = 1km
