How do you multiply a numerator and a denominator?
To multiply a fraction, you simply multiply the numerator (the top number) by the numerator of another fraction and the denominator (the bottom number) by the denominator of the other fraction. The formula can be expressed as: (\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}). This results in a new fraction that combines the two original fractions. Remember to simplify the resulting fraction if possible.
What is formula of fractions?
n / d = q n = numerator d = denominator q = quotient (or answer) It's probably better to think of a fraction as a form rather than a formula.
What is the purpose of using decimals rather than fractions as a whole?
Decimals are easy to compare, add, subtract, multiply, and divide, because they already have a common denominator. You can tell at a glance which is bigger than which. +++ Further the SI, or metric-based, units are based on decimals and powers of 10, so any vulgar fractions in using them arise only when writing real values in a formula.
What is the formula in dividing fractions?
There is no formula for dividing fractions, but there is a way of doing it. When you a fraction divided by another fraction like below... 1/2 divided by 4/7.... Swap the second fraction around and then multiply like this... 1/2 multiplied by 7/4.... And when multiplying fractions, multiply the numerators (top number) together, and the denominators (bottom number) together (1x7)/(2x4) = 7/8 Simple
What is the formula for multiplying fractions?
the easyest way to multiply fractioons is simply by normal multiplication for example. 4/7 multiplyed by 2/3 =8/21

What is the formula for substracting fractions?
There is actually no specific formula to subtract fractions but rather a method to accomplish this. First you have to obtain a common denominatior between the two fractions in order to subtract. This is easiest when you just multiply the denominators. If you have 1/4 and 1/9 you multiply the denominator to have a common one. This would give us 36. then you would have to multiply the numerators by the number you multiplied the denominator. This means that 1/4 would become 9/36 because you multiplied the bottom by 9 in order to get 36. You can check to see if you did this right by simplifying the fraction and seeing if you got your original fraction. Once you have these new common fractions you simply subtract the numerators and put them over the common denominator. 9/36 - 4/36 = 5/36 which cannot be simplified

What is the formula to convert fraction to percantage?
Multiply the numerator of the fraction by 100 and then divide (using long division if needed or a calculator) by the denominator.

Formula for multiplying fractions?
( A/B ) x ( C/D ) = ( A x C )/( B x D ) -- The numerator of the product is the product of the numerators. -- The denominator of the product is the product of the denominators.
What are some methods for changing fractions to a percent?
Well if you have a calculator, simplify the fraction to a decimal. Basically just type it in and hit enter. Then multiply be 100. That's your percent. If no calculator, multiply both the top and bottom of the fraction by the same number; one that will make the bottom equal 100. You can find this number by dividing 100 by the denominator (number on bottom). For example: 3/4 is 75%. To find this, divide 100 by 4 (the denominator), then multiply the answer (25) by the numerator (top number: 3) 25•3=75. The formula for this would be x/y=((100/y)•x)%

How do you solve a graph formula that has fractions in it?
the graphs have fractions on the y axis
How do you find the Fractions and Volume?
To find a fraction of a quantity, divide the quantity by the denominator and then multiply by the numerator. For example, to find ( \frac{2}{5} ) of 20, divide 20 by 5 to get 4, then multiply by 2 to get 8. To calculate volume, use the appropriate formula based on the shape: for a cube, it's ( V = a^3 ) (where ( a ) is the length of a side), and for a cylinder, it's ( V = \pi r^2 h ) (where ( r ) is the radius and ( h ) is the height). Always ensure you have the correct units for your calculations.
When multiplying fractions do you have to have a common denominator?
you don't need a CD for multiplication. only division.you do need a common denominator duhhh* * * * *No, you do not need a common denominator for multiplication or division. But you do need it for addition or sutraction.no you do not. You don't need one in division either. A common denom is only used in addition and subtraction.a equation for multiplying would beA a A*a-- * -- = -----B b B*bDividing is similar, just multiply by the inverse.A a A*b-- / -- = -----B b B*aAdding and subtracting are a little more complicated. Here is a formula to make finding the common denominator easy.A a (A*b)+(a*B)-- + -- = ---------------B b B*bA a (A*b)-(a*B)-- - -- = ---------------B b B*b
