If a fraction is equivalent to one-half then the numerator is always half the denominator. Or, the double the numerator is the denominator.
So, given any other fraction, p/q,
if 2p < q then the fraction < 1/2
if 2p = q then the fraction = 1/2
if 2p > q then the fraction > 1/2

How do you solve a fraction problem when you don't have the same denominator?
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
Why are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
How do you compare 3 or more fractions?
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
Equivalent fractions using least common denominator?
In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12
How can you tell if two fractions are equivalent?
Two fractions are equivalent if the fully simplified fractions are equal. If you can multiply the fraction with the smaller numerator and denominator by the same value to equal the second fraction. For example the fractions 3/4 and 9/12. The nominator and denominator, 3 and 4 have both been multiplied by 3 to equal 9/12. Cross multiply. If the products are equal, the fractions are equal. Cross multiplying means to multiply each numerator of one fraction with the denominator of the other fraction.
How could you use the relationship between the numerator and denominator of fractions equivalent to one-half to determine if a fraction is equal to one-half?
The denominator must be double the numerator.
How could you use the relationship between the numerator and denominator of fractions equivalent to one half to determine if a fraction is less than one half?
If the denominator is more than double the numerator, then the fraction is less than a half.
What do you do when comparing fractions and the denominator and the numerator are different?
Convert them into equivalent fractions with the same denominator and then compare the numerators.
Find a common denominator for the pair of fractions. Then, write equivalent fractions with the common denominator?

How do you add fractions with unlike denometiors?
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
Can you call 2 equivalent fraction like fractions?
No. Like fractions have the same denominator.
How can you tell if fractions are equivalent?
Divide the denominator into the numerator. If the answers are the same decimal, the fractions are equivalent.
Why the you have to multiply the numerator and the denominator to get the equivalent fraction?
That is how equivalent fractions are defined!
Adding and subtracting unlike denominators?
Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).
Are improper fractions integers?
No, they are improper fractions. They can be equivalent to integers if the numerator is a multiple of the denominator.
