The common denominator of any two or more whole numbers, such as 5 7 and 8, 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.

How do you rewrite 5 over 8 and 7 over 10 with the least common denominator?

What is three fourths minus five eighths?
First you need a common denominator: 3/4 and 5/8, the common denominator is 8. (4x2=8, 8x1=8) Multiply both the numerator and denominator of 3/4 by 2 so that it becomes 6/8. Now that a common denominator is established, you may subtract them with ease. 6/8 - 5/8 = 1/8.
How do you take 1 over 8 from 1?
1 - 1/8 First convert both to common denominator. 1 = 8/8 1 - 1/8 = 8/8 - 1/8 Next, subtract the numerators. 8 - 1 = 7 Put the difference between the numerators above the common denominator. 8/8 - 1/8 = 7/8 7/8 is your answer.
