Got a calculator? Then let’s travel to the land of fractions and decimals. To be clear never think that a calculator is a way out of getting out of knowing what you are doing! As a math teacher I can’t tell you how many students trusted their calculators only to discover the pain of a poor test or quiz grade. However calculators are great “tools” to save time and obtain accurate answers. Now to our topic of fractions and decimals. If you want to convert a fraction to a decimal just divide the numerator (the top number in the fraction) by the denominator (the bottom number) see the example below. To convert a decimal to a fraction is a little more tricky. First if a decimal never ends like .782390128634…. we call this a non-terminating decimal and it means we can’t convert it to a fraction. However decimals that end like .3 we can convert to a fraction. The key to convert a decimal to a fraction is to know how to read the place values in a decimal. So in our example .3 is this same as “three tenths”. By reading the decimal as a word like “three tenths” we can write an equivalent fraction. So in this case “three tenths” is equal to 3/10. we say the decimal and fraction form the same way. Remember fractions and decimals are everywhere in algebra so you need to master them to be an ace math student.
