Answer (3)
Just invert it like: 7 ∗ 13 = 91 13 ∗ 7 = 91
There you have your common denominator! Don't forget to multiply the numerator as well.
To find the common denominator of ¾ and ⅓, we can start by listing the multiples of each denominator and identifying the lowest common multiple (LCM). The denominators in this case are 7 and 13. We can find the multiples of 7 by multiplying it by 1, 2, 3, and so on: 7, 14, 21, 28, 35, ... The multiples of 13 are: 13, 26, 39, 52, 65, ... The first common multiple of 7 and 13 is 91. Therefore, the common denominator is 91.
To find a common denominator for 7 6 and 13 5 , the lowest common multiple of the denominators 7 and 13 is 91. Thus, the common denominator is 91. You can convert both fractions to this common denominator for further operations like addition or comparison.
