Krystal`s Scribe for January. 14, 2010

Decimal to Percent=You just have to move the decimal 2 places to the right.Another way to do it is to multiply it by 100. For example. 1.25X100 =125. Just add the percent sign. I find it way easier by doing it with multiplying by 100.

Fraction to Percent= The way I learned was a little different.Since fractions is the same as division, I just divide the fraction number and get the percentage. For example . 61 over 100= 61 divided by 100 = 0.61,just add the percent sign.

Decimal to Fraction= When a decimal has 2 numbers after the decimal it`s out of 100, if it only has 1 number after the decimal, its out of 10, if it has 3 numbers after the decimal it`s out of 1000.ect.For example. 0.005= 5 over 1000. But if its a decimal like this "3.2", 3 is the whole and 2 is out of 10 since it`s the only number after the decimal.the fraction would be , 3 as the whole and 2 over 10.Don`t forget to simplify so it would be , 3 as a whole and 1 over 5. To simplify it , just divide it by 2.

Fraction to Decimal= Remember, a fraction is division turned up-right. That means if the fraction was, 7 over 10, side-to-side would be, 7 divided by 10 =0.7 . Easy,right ? But what if your fraction has a whole number ? for example : 1 and 1 over 4, since the 1 over 4 is simplified, think of it as not simplified "25 over 100" = 25 divided by 100 = 0.25. Take the ".25" and do nothing to the whole number,Then you have "1.25". Sorry, I tried explaining it as best as I could. It`s really easy if you understand what I`m talking about.

BY THE WAY ! Sorry it`s late...
