To determine

To calculate: The smaller number among the numbers 0.008;0.0009.

Explanation

Given Information:

The numbers are:

0.008;0.0009

Formula used:

Steps to compare the decimal numbers:

Step 1: Convert the decimal number into scientific notation.

Step 2: Compare the exponent of the base 10 (power of 10), smaller the exponent smaller will be the number.

Step 3: In case, if the exponents are same, compare the part of the number between 1 to 10. Smaller the number smaller will be number being compared.

Calculation:

Consider the numbers:

0.008

First non-zero digit is at 3rd place from the decimal. Therefore, the exponent of 10 will be 3.

0.008=8.0×103

And,
