Question

1. What is the width of a piece of paper in meters and millimeters if it is 20 centimeters?

2.What is the height of a woman in centimeters and millimeters if it is 1.52 meters?

Answer 1

1. 0.20 m, 200 mm

2. 152 cm, 1520 mm

Explanation:

You may be familiar with a place-value chart that names the digits of a number based on their relationship to the decimal point. It might look like ...

(units) . (tenths) (hundredths) (thousandths)

So a number like 0.2 units can be rewritten in terms of hundredths or thousandths like this:

0.200 units = 20.0 hundredths = 200. thousandths

The name that's attached depends on where you put the decimal point.

___

When the units are meters, the corresponding names are ...

(meters) . (decimeters) (centimeters) (millimeters)

1. That is 0.200 meters = 20.0 centimeters = 200. millimeters.

2. 1.520 meters = 152.0 centimeters = 1520. millimeters.
