How do you do subtract mixed number?
To subtract mixed numbers, convert the fractions into ones with a common denominator, make the first fraction larger than the second, subtract, then reduce the result if necessaryExample : 6 1/8 - 2 3/4Find the common denominator -- here it is 81/8 = 1/8 and 3/4 = 6/8 (you cannot subtract the fractions because the second is larger)So borrow from the whole number by making 6 1/8 into 5 9/8 (1= 8/8)Now 5 9/8 - 2 6/8 can be subtracted to yield 3 3/8---* More on "borrowing" to make the fraction larger : what you are doing is turning one of the whole numbers into an equal fraction and adding it to the fraction. Here we took 1 from the 6 making it 5, and added that 8/8 to the 1/8 to make the improper fraction 9/8. So the terms 6 1/8 and 5 9/8 have the same value.
How do you use LCM in fractions?
Lowest Common MultipleThe smallest common multiple of two or more numbers is called the lowest common multiple (LCM). E.g. Multiples of 8 are 8, 16, 24, 32, …Multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, …In general:To find the lowest common multiple (LCM) of two or more numbers, list the multiples of the larger number and stop when you find a multiple of the other number. This is the LCM.Example 3Find the lowest common multiple of 6 and 9.Solution:List the multiples of 9 and stop when you find a multiple of 6.Multiples of 9 are 9, 18, …Multiples of 6 are 6, 12, 18, …Example 4Find the lowest common multiple of 5, 6 and 8.Solution:List the multiples of 8 and stop when you find a multiple of both 5 and 6.Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, …Stop at 120 as it is a multiple of both 5 and 6.So, the LCM of 5, 6 and 8 is 120.
