Dividing complex numbers | Imaginary and complex numbers | Precalculus | Khan Academy
By Khan Academy
Here we see a guided example of how to divide two complex numbers. Remember to use the complex conjugate of the denominator. The whole point is to make the denominator into a real number, so if that doesn't happen, go back and check over your work very carefully.
Dividing a whole number by a fraction
By Brian Mclogan
To divide two fractions, we multiply the first fraction by the reciprocal of the second fraction.

This lesson covers commutative property of multiplication, which states that a x b = b x a. For example, 10 x 4 = 4 x 10.
Stem and Leaf Plot
By Turtlediary
A stem and leaf plot shows a large amount of data in a clear way by listing it in order of place value. A stem and leaf plot is generally used when data has multi-digit numbers. In this kind of plot, the ones digit of each number in the data is separated from the other digits. The plot has two columns. The first column, called the “stem”, lists all of the digits in the tens place and beyond, in order. A vertical line divides the stem from the “leaves” (the second column). This second column shows the ones place of each number in the data, also in order. Every number in the leaf column represents a number from the data. Its ones place is in the leaf, and the tens place and beyond are in the stem.
Complex Numbers - Multiplying and Dividing

Multiplying and dividing with significant figures | Decimals | Pre-Algebra | Khan Academy
By Khan Academy
This video takes us through some real world examples of when we should use significant figures when multiplying and dividing. An important note: never consider significant figures until you have reached your FINAL ANSWER. Otherwise, rounding too early will produce more uncertainty about your solution.
