How Do You Do Basic Math Fractions?
In elementary school, students are introduced to the world of fractions at a very basic level–adding, subtracting, multiplying and dividing. As you advance in your math studies, you learn more complicated use of fractions in subjects, such as algebra and trigonometry. An understanding of the basic fraction fundamentals can lay the groundwork for future math studies. Add fractions that have common denominators by adding the two numerators together and placing that sum over the common denominator. For example, in the equation 1/4 + 2/4, there is a common denominator of 4. Adding the two numerators together equals 3. Place the 3 over the common denominator of 4 to equal 3/4. Subtract fractions with common denominators by subtracting the two numerators and placing them over the common denominator. For example, in the equation 15/8 – 4/8, you subtract 4 from 15 to get 11; place the result over the common denominator to get 11/8. Simplify the fraction to its lowest form by dividing the deno
