Question

Within the metric system all units are based on the number

a. 1000.
b. 100.
c. 10.
d. 1.

Answer 1

C. The metric system is based on the number 10.

10 centimeters = 1 decimeter
10 decimeters = 1 meter

Answer 2

d. 1

Explanation:

Lets looks at conversions used in the metric system to determine what number it is based on.

1 m =10 cm = 1000 mm

1 kg = 1000 g

1 km = 1000 m

There are more examples but to determine metric units you will use a 1 to a certain conversion factor to determine the correct amount in metric units.

Therefore the metric system is based on the number 1 to convert a certain unit of measurement.
