Dividing decimals - Metric units - IntoMath
In this lesson you will learn and practice a very important skill of dividing decimals using long division. For example, dividing 2.34 by 2 or 34.5 by 0.4.
It is important to understand the place value well and how it affects the final answer.
Sometimes it makes sense to convert a decimal into a fraction to perform division.
0.2 is the same as 2/10
84 divided by 0.2 is the same as 84 multiplied by 10/2, which results in 420.
You will also learn how decimals are related to unit conversions (between systems and within each system – metric, imperial, etc).
We focus on converting metric units of length and mass – cm to m, kg to g and so on. For example, 1000 grams is equal to 1 kilogram, thus 0.001 kilogram is the same as 1 gram.
