Proper, Improper and Mixed Fractions
A proper fraction has a numerator less than its denominator, an improper fraction has a larger numerator, and a mixed fraction is a combination of a whole number and a proper fraction.
Multiplication of Fractions
To multiply two fractions, simply multiply their numerators together to get the new numerator, and their denominators together to get the new denominator.
Division of Fractions
To divide a fraction by another fraction, multiply the first fraction by the reciprocal (inverse) of the second fraction.
Multiplication of Decimals
Multiply decimal numbers as whole numbers, then place the decimal point in the product by counting the total number of decimal places in the multiplier and multiplicand.
Division of Decimals
Shift the decimal point of both the dividend and divisor to the right by the same number of places until the divisor becomes a whole number, then proceed with normal division.

Frequently Asked Questions
How do I find the reciprocal of a mixed fraction?
First, convert the mixed fraction into an improper fraction, and then flip the numerator and denominator to get its reciprocal.
Why do we change division to multiplication when dividing fractions?
Multiplying by the reciprocal is a mathematical shortcut that yields the exact same result as dividing by a fraction, making calculation much easier.
Where do I place the decimal point when multiplying decimals?
Count the total number of decimal places in all the numbers you are multiplying, and place the decimal point in your answer so it has that same total number of decimal places from the right.
