1. You have to know the base of the original number.

2. If the base of the original number is base 10, then you don't need to convert it to decimal because the original number is already a decimal number. This means the decimal numbering system is base 10 (i.e. it has 10 base digits-->0-9)

3. If the base of the original number is different than base 10, then you will need to use a mathematical conversion method (or a computer program/calculator) to convert the original number to decimal.

For example:

If the original number 1011 is a base 2 (binary) number, then you would use the following conversion method to convert it from base 2 to base 10:

1 * 2^0 = 1 * 1 = 1

1 * 2^1 = 1 * 2 = 2

0 * 2^2 = 0 * 4 = 0

1 * 2^3 = 1 * 8 = 8

Now add the right most column of numbers together (e.g.: 1+2+0+8=11). 11 is the decimal (base 10) equivalent to the original base 2 number 1011.

Similar methods can be used to convert from other base numbering systems to decimal (e.g. base 5 to base 10)

You can either convert fractions to decimals and compare the decimal numbers; find equivalent fractions with the same denominator and then compare numerators or find equivalent fractions with the same numerator and then compare denominators.

Convert them to fractions.

That already is a decimal. No need to convert anything.

Decimals are a way to represent numbers whereas metric refers to a system of measurements. There can be no conversion from one to the other.

Short answer, you don't. Decimals are parts of whole numbers.

Yes - you can always convert numbers to scientific notation - whether they're whole numbers, or decimals.

Convert any mixed numbers to improper fractions. Once you have a fraction (proper or improper) do the division. 2/4 = 2 divided by 4 = 0.5

If you convert them into decimal form you can say there are terminating decimals, there are the integers, and there are repeating decimals. EX: 2.4 is a terminating decimal. 2.44444444... is a repeating decimal. 2 is an integer. all are rational numbers.
