Do you mean like when you're trying to calculate the value of a variable? You divide the numerator by the denominator?
If the operation involves subtracting a numerator from a denominator, then you would be subtracting the numerator.
-2/denominator
You need to:* Find a common denominator (it need not be the least common denominator); * Convert both fractions to the common denominator * After that, you can simply subtract the numerators. * Check whether you can simplify the result.
Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.
Find the "common denominator". 2/5 is 6/15. So 1 fifteenth minus 6 fifteenths is minus 5 fifteenths , or minus one third
(15/2 minus 5/8) becomes (60/8 minus 5/8) by finding the common denominator of the two fractions. By using the laws of subtracting fractions, 60 minus 5 equals 55, and the denominator remains the same, 8. So, the answer is 55/8, or 6.875.
Multiply the numerator and denominator by the complex conjugate of the denominator ... [ root(2) minus i ]. This process is called 'rationalizing the denominator'.
y = 1. When the degree of your numerator is the same with the degree of your denominator, then y = the ratio of the leading coefficients of the numerator and denominator is the horizontal asymptote.
3 - 4-1/2 = 6/2 - 9/2 common denominator would be 2.
To subtract fractions, you need a common denominator. In this case, the common denominator is 7. So, 8/14 is equivalent to 4/7. Subtracting these fractions gives us 0. Hence, 4/7 minus 8/14 equals 0.
One sixth. As the denominator (bottom number) is the same on both sides, simply take four away from five, and keep the denominator the same.
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
find the lowest common denominator so both have the same denominator, then subtract the numerators only leaving the denominator the same For example 1/2 - 1/4 2/4-1/4 = 1/4
