This lesson covers adding decimals. Students learn to add decimals by first lining up the decimal points, then adding the numbers by column. For example, to add 14.2 + 2.86, first line up the decimal points, then add the digits in the hundredths column, to get 0 + 6, or 6, then add the digits in the tenths column, to get 2 + 8, or 10, so write a 0 in the tenths column and carry the 1 to the units column, then add the digits in units column, to get 1 + 4 + 2, or 7, then add the digits in the tens column, to get 1. So 14.2 + 2.86 = 17.06.

In this video, students will review the idea that the ratios of the lengths of corresponding sides of similar figures are equal. Students are shown how to use this idea to find missing segment lengths in similar figures.
Law of Sines, Example 3
By PatrickJMT
The Law of Sines, Example 3. In this video, I just another example involving the law of sines. We are given the ratio of the lengths of the angles of the triangle and the length of the shortest side and are asked to find the length of the longest side.

This lesson covers complementary angles. Students learn the definition of complementary and supplementary angles, as well as how to find the measures of the complement and supplement of a given angle. Students are also asked to solve word problems in the following form: "If the ratio of an angle to its complement is 2:3, find the measure of each angle."
Solve Problems Involving Rates and Ratios
By Khan Academy
Watch this video as the instructor clearly explains how to solve a word problem involving finding unit rates. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. See how you can apply this process to help you solve similar problems.
