Question

A work ladder can extend to 8 meters. How many centimeters is that? How many kilometers is that? Use 1000 m) unit analysis to solve this conversion problem (1 km ==​

Answer 1

8m = 800cm

8m = 0.008km

Explanation:

1 kilometer is 1000 meters

1 meter is 100 centimeters

You'd only have to multiply in the first one:

`8 * 100 = 800`

8m = 800cm

Remember that when multiplying by 100 you only have to add zeros.

For km, as it is bigger than m you have to divide by 1000, when dividing this time you only have to carry an imaginary point starting from right to left, the amount of zeros there are:

`8. \\ .8 \\ .08 \\ .008 \\ 8 / 1000 = .008`

8m = 0.008km

If you run out of numbers when carrying the point, just add zeros.
