You do the same as what you would do if they were integers.
If you want 8 - 12, the answer is -(12 - 8) = -4.
You take the smaller away from the larger and put a negative sign in front.
Because it's a fraction
an irregular fraction is a fraction where the numenator is larger than the denomenator
One seventh is larger than one eighth. The smaller the number under a 1 in a fraction, the larger that fraction is. Think 1/4, 1/3, 1/2 and you'll see the size of the fraction increasing; the numbers are becoming larger.
improper
No, a proper fraction has a numerator smaller than the denominator.
It is called "writing a fraction as an equivalent fraction with a larger denominator"!
The name of a fraction with a larger number on top is called an improper fraction.
When the fractions are converted to equivalent fractions with the same denominator the one with the larger numerator is the larger fraction.
A fraction can be larger than 1, for example, 4/2 is a fraction (which can be simplified to 2). Only a fraction that is larger than 1, multiplied by another number gives you a larger number.
an improper fraction
The quotient is larger than the original fraction.
the numerator
It is closer to us than the other stars so we get a much, much larger fraction of its light compared to other stars. The other stars are so far away that even stars that are much brighter than our sun can only transmit such a small fraction of their light that the tiny fraction we get is consequently much less than the larger fraction of our somewhat dimmer sun.
