1/2 as a decimal and as a percentage

Here is your fraction:

You need to change it into:

DECIMAL

Let's start with decimal. To change a fraction into a decimal, divide the numerator(number on the top of a fraction) by the denominator(number in the bottom of a fraction). In this fraction, the numerator is 1 and the denominator is 2. That means you need to divide 1 by 2.

Divide:

Your answer as a decimal is 0.5

PERCENTAGE

To change a fraction into a percentage, it's easier to have the decimal form. We have already found the decimal form, which is 0.5. Now, all you need to do is move the decimal point 2 places to the right and add a percent sign.

First move the decimal point 2 places to the right:

Now add the percent sign:

Your answer as a percent sign is 50%

Decimal: 0.5

Percent: 50%

Remember:

Fraction to decimal → Divide the numerator(number on the top of a fraction) by the denominator(number in the bottom of  fraction)

Fraction to percentage → Find the decimal form. Then move the decimal point 2 places to the right and add a percent sign.
