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.
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
The standard deviation.z-score of a value=(that value minus the mean)/(standard deviation)
