Learn how to solve fraction example | easy tricks | vijay mathslink : youtu.be n9renlzr4hq. To add fractions, they must have the same denominator. if they do, simply add the numerators together. [2] for instance, to solve 5 9 1 9, just add 5 1, which equals 6. the answer, then, is 6 9 which can be reduced to 2 3. 2. subtract fractions with the same denominator by subtracting the numerators.
Step two: add the numerators together and keep the denominator. now we have a new expression where both fractions share a common denominator: 1 4 1 2 → 2 8 4 8. next, we have to add the numerators together and keep the denominator as follows: 2 8 4 8 = (2 4) 8 = 6 8. step three: simplify the result if possible. We need to add 2 7 and 3 9. the common denominator is 7 times 9 = 63. the next step would be to replace each fraction's own denominator with the common one. for the first fraction, 63 divided by 7 = 9 and 9 times 2 = 18. the result is 18 63. for the second one, 63 divided by 9 = 7 and 7 times 3 = 21. Example 1: adding fractions with like denominators. solve \, \cfrac {5} {8} \cfrac {7} {8} \, . add or subtract the numerators (top numbers). since the denominators are the same, the parts are the same size. you add to see how many parts there are in total: 5 7 = 12. 2 write your answer as a fraction. Examples: 3 8, 1 2, 7 9. improper fractions. definition: an improper fraction is a fraction with a numerator that is greater than the denominator. for example, 7 5 is a proper fraction because 7 > 5. the value of an improper fraction is always greater than one whole. examples: 5 2, 12 11, 9 4. mixed fractions.

Word problems with fractions: involving a fraction and a whole number. finally, we are going to look at an example of a word problem with a fraction and a whole number. now we will have to convert all the information into a fraction with the same denominator (as we did in the example above) in order to calculate. 2. multiply the numerators and denominators. multiply the fractions straight across to multiply the numerators. put the result over a dividing line and multiply the denominators. put the result under the dividing line. [9] to continue the example, you'd multiply 5 4 by 2 1 to get 10 4. 3.
