% means divided by 100 so you just move the decimal 2 places to the left & drop the % sign
7.8%=.078

The percentage sign is just a way to express a number as a fraction of 100. So, 7.8% means 7.8/100. To write this as a decimal, simply divide 7.8 by 100. There's not a good way to show the steps in the space provided. Dividing 7.8 by 100 gives you the answer 0.078.

Well, percentages are out of 100, right? So you can write 7.8% like this:
7.8/100
When you divide by 100, you just have to move the decimal to the left two places (one place for every zero). That gives you:
0.078

7.8% is the same as 0.078.
The simple rule is move the decimal point two places to the left.
Another is to divide the percentage (7.8%) by 100.
7.8/100 = 0.078

To make a percentage to a decimal, move the decimal point 2 places to the left.
7.8% = .078
If this is too hard for you, algebra will murder you. Read your textbook.

Simply remove the % sign and move the decimal point two places to the left to get 0.078.

7.8% = .078
Move the decimal place two decimal places.
If it was 100%, it would be 1.00
10% equals .10

% means percent that means per 100, so:
7.8/100 = 0.078.

0.078...to convert a percentage to decimal, just divide it by 100...multiply by 100 if you want to convert decimal to percentage.
