When we want to convert a percentage to a decimal, we simply move the decimal point two places to the left. Therefore, to convert 13% to a decimal, we need to move the decimal point two places to the left.

**Step 1: Write down the percentage as a fraction To convert a percentage to a fraction, we need to write the percentage as a fraction with a denominator of 100. For 13%, this would be:**

13/100

**Step 2: Simplify the fraction (if possible) In this case, the fraction is already in its simplest form.**

**Step 3: Convert the fraction to a decimal To convert a fraction to a decimal, we divide the numerator by the denominator. Therefore, for 13/100, we get:**

13 รท 100 = 0.13

Therefore, 13% as a decimal is 0.13.

Alternatively, we can use a shortcut to convert a percentage to a decimal. We move the decimal point two places to the left and drop the percent sign.

For example, to convert 13% to a decimal, we can move the decimal point two places to the left:

13% = 0.13

Therefore, 13% as a decimal is 0.13.

In summary, to convert a percentage to a decimal, we divide the percentage by 100 or move the decimal point two places to the left and drop the percent sign.
