The common denominator of any two or more whole numbers, such as 4 5 13 and 17, 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.

### What is -13 - -17?

It is -13 - -17 = 4

### To subtract two rational expressions that have a common denominator you simply the numerators?

Yes, eg 13/17 - 4/17 = 9/17

### What is the common denominator of 12 6 and 4?

There are infinitely many common denominators. The least of these is 12.

### What is greater 3 over 4 or 13 over 15?

I don't know, so I need common denominators to compare fractions. One has to go all the way to 60 here. 15*3/15*4 = 45/60 ------------ 4*13/4*15 = 52/60 -------------- so, 13/15 &gt; 3/4 -----------------------

### What is three fourths minus of one half?

in order to answer this problem you have to first make the denominators (bottom number) match.Do this by finding the smallest common multiple (the smallest number that both of the denominators divide into) of the denominators.3/4 - 1/23/4 - (1/2) x 2 (4 is the smallest common multiple of 2 and 4. Multiply 1/2 by 2 so that the denominators match)3/4 - 2/4 (now you just subtract the numerators (top number). leave the denominators as they are.)3/4 - 2/4 = 1/4
