Fractions to Decimals & Fractions to Percents

Hi Ellie,

You're going to do really well on your test. It may not feel like it right now but you will. Sometimes taking tests can be scary. It can feel like a LOT of pressure on you to do well. When you get anxious and scared it's hard to think clearly and then you don't do as well as you are able. Imagine a kitten chasing its tail -- that's kind of what it's like. Stay calm and Don't Panic. You'll be able to do your best that way.

Another way to make sure you can stay calm is to prepare well. I think these are the last two topics you're still feeling uncertain about so lets take care of that right now. :-)

First, read this. Scroll down to the middle of the page to find the sections on Fraction to Decimal and Fraction to Percent. I know that's not your favourite way to study but it's really well written. There are lots of examples, solved step-by-step, and each step is explained in words and numbers.

Now to practice your skills:

(1) Go here. You type in a fraction, first the numerator (top number) then the denominator (bottom number).

(2) To change the fraction to a decimal do the long division on scrap paper going to as many decimal places as your teacher usually asks for in class.

(3) When you're done, or if you get stuck, type in the number of decimal places you want and click [Convert it]. The computer will show you all the steps in the long division. If you got it right, GREAT! Try another one. If you got it wrong look CAREFULLY at where you made the mistake and compare what you did to the right answer on the computer. Then try another one.

(4) Go ahead and "make up" your own questions. Keep doing this until you feel good about it. Don't give yourself a time limit. Keep at it until you feel you've got it or you get "that bad feeling in the pit of your stomach." If that happens, take a break and come back again later.

Fractions to Percents
First change the fraction to a decimal, like you did above. Then, multiply by 100 and put a % at the end. Multiplying by 100 is the same thing as "moving the decimal two places to the right."

To practice, you can use the same link as above to change the fraction to a decimal. To see if you changed it to a percent correctly go here.

Enter the fraction (you can even do mixed numbers here). From the popup menu below it select "Display result as [a percent]" then click the [simplify] button. (It's a good idea to uncheck the "Results on a new page" box.)

Don't email me, CALL ME as soon as you hit a snag. I KNOW you can do this Ellie. Yes, it can be hard, very hard, but don't give up! You're going to conquer this stuff!

Love ya!

    You must have taken the test by now.

    How are you feeling about it?

    Did you feel like a cat chasing her tail or were you okay about it?

    What strategies did you use to study?

    What test will you do next?

    I wish you good luck and everything, and your Uncle too.
