5/15
It is if: * the numerator is greater than half the denominator. * twice the numerator is greater than the denominator. * the denominator is less than half the numerator. * twice the denominator is less than the numerator. * the decimal equivalent is gretaer than 0.5. * if you subtract 1/2, the answer is positive. * if you subtract it from 1/2 the answer is negative. * the square of the number is between greater than 1/4. There are many more.
17/(2*17+2) = 17/36
It is 6/15.
Yes, it can be. If the numerator is 0. Then suppose the denominator is 3, which is bigger than 0 (double the numerator). So the value of the fraction is 0/3 = 0.
Whatever you multiply or divide the numerator by, you must do the same to the denominator. If you multiply or divide the numerator and denominator by different numbers, you change the value of the fraction and turn it into a different number. After that, nothing is "equivalent" any more ... you're working with a changed number.
3 over 6 3/6! easy then reducce it to 1/3 :)
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
If the denominator is more than double the numerator, then the fraction is less than a half.
A "common denominator"
I assume you are talking about equivalent *to another ratio*. Equivalence means that two (or more) things mean pretty much the same thing. For ratios to be equivalent, that would mean that when they are reduced (by factoring out any common multiples of the numerator [top part] and denominator [bottom part]) they become the same ratio. Case in point: 1/2 is equivalent to 2/4 (which is 1/2 when you factor out a 2 from the numerator and denominator.) 1/3 is equivalent to 3/9 (which is also 1/3 when you factor out the 3 from the numerator and denominator.)
Example: 2/3 and 3/4 The LCD of 3 and 4 is 12. Multiply the numerator and the denominator of 2/3 by 4 to make 8/12 Multiply the numerator and the denominator of 3/4 by 3 to make 9/12
If you mean the steps, they are as follows:* Identify a common denominator. Any common denominator will do. * Convert both fractions to equivalent fractions, with the common denominator found in the previous step. (If the fractions start off with the same denominator, there is nothing else to do in these first two steps.) * Add the numerators. That's the numerator of the result. Copy the common denominator as the denominator of the result. * Check whether you can simplify the resulting fraction.
