Welcome to the Algebra II/Trigonometry portion of the site!  On this and the following pages, we'll try to clear up some common problems people have with intermediate algebra (Algebra II) and trigonometry (which ought to have a class of its own just to learn how to pronounce it).  Everything from solving basic equations to the trigonometric ratios are covered.

Converting a decimal into fraction could not be easier. (there is a solver for this in this module, also). A decimal such as 2.34 has two parts, 2 and .34. 2 is the integer part and .34 is the fractional part. The fractional part is an abbreviation for a fraction with the base (denominator) of 1 plus as many zeroes as there are digits in the fractional part. for .34, with TWO digits, the denominator is 1 followed by TWO zeroes.

2.34 = 2 34/100

The only step that you need to take is to possibly reduce the fractional part. In the example above, both 34 and 100 are divisible by 2. So, the fractional part reduces to 17/50.

2.34 = 2 34/100 = 2 17/50
