#### Worksheet Overview

Using standard form is incredibly useful when we need to use either very large or very small numbers.

Areas we may use standard form include physics, biology and chemistry. From measuring the distance between planets to the mass of atoms.

In this activity, we will use inequalities to compare numbers written in standard and ordinary form.

Example

Complete the expression using <, > or =

2.5 x 102 260

With this type of question, it is best to convert one of the values into the same form as the other.

2.5 x 102 = 250

Now we can compare.

250 < 260

2.5 x 102 260

Example 2

Complete the expression using <, > or =

1.9 x 10-2 ? 0.19

With this type of question, it is best to convert one of the values into the same form as the other.

1.9 x 10-2 = 0.019

Now we can compare.

0.019 < 0.19

1.9 x 10-2 < 0.19
