![]() ![]() Previous Adding and Subtracting Fractions Next. ![]() Lets look at some examples of adding fractions using this procedure. The second method is only applicable when the larger mixed number has a smaller proper fraction than the smaller mixed number. To subtract a mixed number from a whole number, you have to borrow from the whole number. Procedure: To add two or more fractions that have the same denominators, add the numerators and place the resulting sum over the common denominator. But if the proper fractions have unlike denominators, get the LCD and change the fractions into equivalent fractions using the LCD as the denominator then subtract the numerators and remain the LCD as the denominator. To get the whole number into the fraction, we need to multiply the whole number (1) by the denominator of the fraction. If the proper fractions have similar denominators, subtract the numerators directly and remain the denominator as it is. By adding the fractions we are grouping the total number of wholes and parts. Subtract the whole number of the smaller mixed number from the whole number of the new larger mixed number. The 4 in the denominator tells us that each whole is cut into 4 equal portions. The new larger mixed number will be a whole number added by a mixed number with 1 as the whole number.Ĭhange the mixed number (with 1 as the whole number) into an improper fraction. Second Method If the larger mixed number has a smaller proper fraction than the smaller mixed number, subtract the whole number of the larger mixed fraction by 1 and add 1 to the proper fraction.īy adding 1 to the proper fraction, it will become a mixed number. ![]() Subtract the numerators and remain the LCD as the denominator. If the proper fractions have unlike denominators, get the LCD and change the fractions into equivalent fractions using the LCD as the denominator. Simplify and convert the differences to mixed. First Method Convert the mixed number into an improper fraction. Multiply the denominator with the whole number, let the denominator be common for both the numbers, and subtract. ![]()
