![]() When subtracting fractions with unlike denominators – 2/ 5 and 3/ 10 – repeat the procedure from the previous section, but subtracting, not adding in the final step:Įxpand the fractions to their equivalent fractions with a common denominator: 4/ 10 and 3/ 10. If you have fractions with the same denominator, subtract the numerators: If you're wondering how to subtract fractions, and you've read through the previous section How do you add fractions, we have some good news for you: it's pretty much the same! For 0.35355339059 as a Fraction, multiply the numerator and denominator by 10 for each digit after the decimal point. If you're still wondering how adding fractions works, maybe this visual will help? Of course, our fraction calculator deals with all of these scenarios. ➽ 13/ 5 + 3/ 2 = 26/ 10 + 15/ 10 = 41/ 10įinally, you can convert your result back into a mixed fraction: That's your new numerator – write it on top of your denominator:Īnalogically, you can find out that 1 1/ 2 = 3/ 2.ĭo the standard addition of fractions with uneven denominators: Multiply the whole number by the denominator: One solution for this kind of problem is to convert the mixed fraction to an improper fraction and sum it up as usual. You want to add two mixed fractions – e.g., 2 3/ 5 and 1 1/ 2 You can convert any length unit to inches, but you don't have to remember all the formulas by heart - just use our inches to fraction calculator, and choose one of the most common length units. The Fraction Calculator will reduce a fraction to its simplest form. Now that your fractions have the same denominator, you can add them: 0.0254 0.0254 Then convert this decimal to fraction inches as you've learned from the previous section. Step 1: Enter the fraction you want to simplify. ![]() Your second fraction already has its denominator equal to 10: So, you should multiply the fraction with the denominator equal to 5 (our 1/5) by 2 to get 10 (remember that you must multiply both top and bottom numbers): Then, you need to expand each fraction to have this common denominator as its bottom number: Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. You can use, for example, LCM – the least common multiple to find the common number of your two denominators: LCM(5,10) = 10 Another option is to multiply your denominators and reduce the fraction later. Step 1: Write down the number as a fraction of one: 3.59 3.591. This is a bit more of a complicated case – to add these fractions, you need to find the common denominator. The fractions have unlike denominators – e.g., 2/ 5 and 3/ 10 This is the most straightforward case all you need to do is to add numerators (top numbers) together and leave the denominator as is, e.g.: The denominator (bottom number) is the same in both fractions – e.g., 3/ 5 and 1/ 5 ![]() When it comes to adding fractions, there are three scenarios: ![]()
