Then multiply the numerators to get a numerator and multiply the denominators to get a new denominator.
Quick way to reduce fractions. Find the highest common factor of the numerator and denominator. Divide the numerator and denominator by the highest common factor. 04092014 mathsAdding fractions is probably the first difficult bit of maths we come across at school.
And reduce or simplify the fraction to put it in its lowest terms. 22042016 Just remember to start by factoring the numerator and denominator then rewrite the fraction in terms of these prime factors next cancel out any common factors which is effectively what happens when you divide the top and bottom of the fraction by the common factors and finally multiply any remaining factors together to find the reduced fraction. For example suppose you want to reduce the fraction 1230.
Break down both the numerator top number and denominator bottom number into their prime factors. As others have said you can take out common divisors of the numerator and denominator until there are no longer any common divisors. What is the quickest and easiest way to reduce fractions.
Cross out any common factors. How to Reduce Fractions One way to reduce fractions is to find the greatest common factor of the numerator and the denominator. When numerator and denominator are small it is easy to spot such divisors but when they are large that is not so easy.
It uses the following formulas provided that no denominator is ever zero. Write down the factors for the numerator and the denominator. Determine the largest factor that is common between the two.
Break down both 12 and 30 into their prime factors. Follow the steps mentioned below to reduce a fraction to its simplest form. 1 Take the cross products and addsubtract them.
2 37 and 80. 16022020 To reduce a fraction you find a number that goes into both the numerator the number on top and the denominator the number on the bottom without anything left over in either case. If you are multiplying a fraction by an integer put the integer over one to make a fraction of it.
The fraction so obtained is in the simplest form. 31032015 At last youve found a number that goes into both numerator and denominator. Other examples of fractions that can be further reduced include 312 1620 824.
Here are the steps to follow. You do the division then look for another number that will divide evenly into the new numerator and denominator. For example to work out frac56 frac710 you first need to figure out that the lowest common multiple of 6 and 10 is 30 and that in order to get 30 in the denominator of both fractions you need to multiply the numerator 5 by 5 and the numerator 7 by 3.
And - The steps are as follows. Heres how to reduce a fraction. Contrary to popular belief there is a fast way to add and subtract fractions with unlike denominators and it does not involve finding a common denominator.
7480 gets hacked down to 3740 and that fraction my dear friends.
