Add 1 / 4 + 2 / 4 = 1 + 2 / 4 = 3 / 4 It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 4) = 4.It is enough to find the common denominator (not necessarily the lowest) by
Wealso need to multiply the numerators above the line by the same amounts so that the fraction values are correct: 1 x 2 2 x 2 - 1 x 1 4 x 1. This is what 1/2 minus 1/4 looks like with the same denominator: 2 4 - 1 4. Now that these fractions have been converted to have the same denominator, we can subtract one numerator from the other to make Findthe least common denominator or LCM of the two denominators: LCM of 2 and 4 is 4 Next, find the equivalent fraction of both fractional numbers with denominator 4; For the 1st fraction, since 2 × 2 = 4, 1 / 2 = 1 × 2 / 2 × 2 = 2 / 4; Likewise, for the 2nd fraction, since 4 × 1 = 4, 3 / 4 = 3 × 1 / 4 × 1 = 3 / 4; Add the two like Fractionformat button is used to work with all fractions. Also to change a decimal of the form 0.5 to the fraction 1/2, or change a decimal of the form 1.75 to a mixed number of the form 1 3/4 or to the fraction 7/4, or a fraction of the form 7/4 to the mixed number 1 3/4. Click the fraction format button, enter a decimal, click equals and Algebra 1.4 1.4. Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is 1 1 number to the right of the decimal point, place the decimal number over 101 10 1 (10) ( 10). Next, add the whole number to the left of the decimal. 1 4 10 1 4 10.Sothe answer is that 2 1/4 as a decimal is 2.25. And that is is all there is to converting 2 1/4 to a decimal. We convert it to an improper fraction which, in this case, is 9/4 and then we divide the new numerator (9) by the denominator to get our answer. If you want to practice, grab yourself a pen, a pad, and a calculator and try to convert2 b) Add the answer from the previous step 4 to the numerator 1. New numerator is 4 + 1 = 5. c) Write a previous answer (new numerator 5) over the denominator 2. Two and one half is five halfs. Conversion a mixed number 1 1. /. 4 to a improper fraction: 1 1/4 = 1 1. /. 12. (Four-Eighths) (Two-Quarters) (One-Half) =. =. It is usually best to show an answer using the simplest fraction ( 1/2 in this case ). That is called Simplifying, or Reducing the
Convert1/2 divided by 4 to Decimal. Here's a little bonus calculation for you to easily work out the decimal format of the fraction we calculated. Once you have your final fraction, just divide the numerator by the denominator to get your answer in decimal form: 1 8 = 0.125.
