Numerator of answer = product of numerators.

Denominator of answer = product of denominator.

So a/b * c/d = (a*c)/(b*d)

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

How do you type fractions in Microsoft Word 2003?

Creating fractions in Word depends on if it is a simple fraction, three-fourths for example, or a complex fraction, like the Quadratic Formula. Most simple fractions will automatically be changed to fraction form by Microsoft. Try typing 1/2 in a document and press the space bar afterward and watch it turn to ½. Complex fractions aren't so lucky. You will need to create a table that has 1 column and 2 rows. The first row will act as your numerator and the second row will be your denominator. When you create the table, it will automatically have borders, you will want to remove all the borders and only leave the line between the numerator and the denominator.
