What is the state rule for dividing fractions?
Take the 2nd fraction, switch the denominator with the numerator, multiply across, simplify.
How do you do cross multiplication?
Take the two fractions and put them side to side and multiply the numerator and the numerator and the denominator by the denominator and simplify if needed
How do you divide the numerator by the denominator?
you take the numerator and divide by the denominator. for example, if you had the fraction 1/2 you would divide 1 by 2 giving you 0.5.
What is the reciprocal of 3 over 16?
To take a reciprocal, all you have to do is switch the numerator and denominator. So for 3/16, the reciprocal would be 16/3.
How can you convert a fraction to a decimal?
all you have to do is take the numerator and divide it by the denominator
How can you make a reciprocal out of a mixed number?
First you need to make the mixed number into a improper fraction. To do this, take the denominator times the number in front. Then add the result to the numerator. Then the improper fraction is that result over the denominator. _______________________________________________________________ If X is the leading number, D is the denominator, N is the numerator: X and N/D=(X*D+N)/D _______________________________________________________________ Then take this new fraction and flip the numerator and the denominator: D/(X*D+N) _______________________________________________________________ So to get the reciprocal of a mixed number in one step, the reciprocal's: numerator is equal to the denominator of the mixed number; denominator is equal to the leading number multiplied by the denominator added to the numerator.
How do you convert fractions and whole numbers into decimals in the easiest way?
The easiest way is to take a calculator, and divide the numerator by the denominator. If you are not supposed to use a calculator, divide the numerator by the denominator on paper.
How do make an equivalent fraction?
Take the fraction you have, and multiply the numerator and denominator by the same number.
How do you write a linear equation?
you have to take the bottom denominator and multiply it by the numerator then go bang a bum
How do you change mixed numbers to improperfractions?
You take the whole number, multiply that by the denominator, then add the numerator. Whatever number you get, put that over the original denominator. Example: 2 3/4 2 (whole) x 4 (denominator) + 3 (numerator) = 11. Take 11 and put it over the denominator (4) you'd get 11/4 Hope this helped :)
How is a numerator different from a denominator?
The numerator tells how many of something, and the denominator tells the size of the "something". Take a pizza and cut it into 8 pieces. Each piece is one eighth, or one of eight (1/8), so 8 is the denominator. If you take 3 pieces, you now have three eighths (3/8) of the pizza.
What is the reciprocal of twelve percent?
Twelve percent is equivalent to the fraction 12/100. To find the reciprocal of a number, you take its fraction form and switch the numerator (top) and denominator (bottom). So the reciprocal of 12% is 100/12.
