63 is their lowest common denominator, so you should use that. 2/7 = 18/63 and 4/9 = 28/63

Twenty eighths.

3/4+4/7 = 21/28+16/28 = 37/28 = 1 9/28

3/4+4/7 = 21/28+16/28 = 37/28 = 1 9/28

Fractions can be simplified when the numerator and denominator have a common factor in them. If both the numerator and denominator have common factors, then we can cancel these factors out. So the simplest for of 18/56 is 9/28.

The common denominator is 28.

the lowest common multiple of 28 and 30 is 420.

The lowest common denominator of any two or more whole numbers, such as 28 and 36, 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.

The lowest common denominator of any two or more whole numbers, such as 26 and 28, 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.

least common denominator of 26 42 and 28 is 1092.

least common denominator of 36 42 and 28 is 252.

The greatest common denominator of any set of denominators is infinite.

Assuming those are denominators of fractions you wish to add or subtract, you can use any common multiple of 4 and 14; the Lowest Common Multiple (LCM), often called the Lowest Common Denominator (LCD) especially when when referring to the denominators of fraction, provides the smallest numerators. For 4 and 14, the LCM is 28.

The lowest common denominator of any two or more whole numbers, such as 3 30 28 and 29, 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.

The LCD for 3/4 and 4/7 is 28.

The Least Common Multiple of 28 and 37 is 1036.

The answer is 28, because 2 can go into 28.
