2* 3 = 5 · 3. /. 2 · 1 = 15. /. 2. Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (15, 2) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - five halfs multiplied by three is fifteen halfs. 12 = 65 = 115 as a fraction. To convert the decimal 1.2 to a fraction, just follow these steps: Step 1: Write down the number as a fraction of one: 1.2 = 1.21. Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. Tovisualize the question we are trying to solve, let's put 1/2 and 3 side-by-side so it's easier to see: 1 2 ÷ 3. So here is the incredibly easy way to figure out what 1/2 divided by 3 is. All we need to do here is keep the numerator exactly the same (1) and multiple the denominator by the whole number: 1 2 x 3 = 1 6. Onceyou've flipped the second fraction and changed the symbol from divide to multiply, we can multiply the numerators together and the denominators together and we have our solution: 3 x 2 4 x 1 = 6 4. You're done! You now know exactly how to calculate 3/4 - 1/2. Hopefully you understood the process and can use the same techniques to add other Pleasesee below. . There are infinite number of fractions that are equal to 1/3. You can multiply the numerator and denominator of 1/3 by any number and the So1/2 of 1/3 = (1/2 ) (1/3) = 1/6, where you multiply the numerators and denominators separately. For example, (a/b) (c/d) = (ac/bd) and then simplify or reduce it if you can for common factors on top & bottom. BTW. If you have trouble with fractions, think of a familiar metaphor like a pizza pie. Initially, it gets cut into 3 equal parts. Averageof Fractions Calculator. Answer: Average = 47 48 A v e r a g e = 47 48. Showing the work. To find the average add up the values and divide the sum by the number of values. Rewriting all values as fractions, rewriting any negatives if necessary and, setting up as an addition problem. Threeand one half is seven halfs. a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3. b) Add the answer from the previous step 3 to the numerator 2. New numerator is 3 + 2 = 5. c) Write a previous answer (new numerator 5) over the denominator 3. One and two thirds is five thirds. 8qtzs.
