20, although if you reduced 15/20 to 3/4, the common denominator would be 4.
The common denominator of any two or more whole numbers, such as 100 and 150, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
lowest common denominator of 4/5 and 7/15 would be 15 4/5=12/15
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
Least common denominator. Used in fractions. For example : 1/2 and 3/4 The fraction that has the lowest denominator, while still having an equivalent fraction is the LCD. In this case it would be 2/4 and 3/4. Because 1/2 = 2/4, and the lowest common denominator between the two fractions is 4. Hope this helps ! :D
22. you would have 18/22 and 11/22
the lowest common denominator is 70 the numerators would become 63 and 30
You need to make a common denominator. In this case the easiest would be 35 (7x5) Then 'what you do to the bottom you do to the top' 15/35 = 3/7 14/35=2/5 Therefore three sevenths is larger.
What would be the ideal Common Denominator for 2 and 4?
The least common denominator would be 36
your common denominator would be 105
your common denominator would be 105
The lowest common denominator would be twelve!
A seventh is, in common math, 1 divided by 7. As this show, a full 7 sevenths would equate to 1. Thus, we can conclude that there is no way that 3 sevenths can be 9, as it is less than 7 sevenths.
A common denominator results from comparing two or more unlike denominators. It can be the same as one of the denominators, but doesn't have to be.
The least common denominator would be 50
the bottom number in a fraction. e.g. in 3/6, the common denominator would be 6. in 45/78, it would be 78. the common denominator must be the same in both fractions when adding or subtracting them from/ to each other.
