The Fibonacci sequence is a series of numbers in which a given number is the addition of the two numbers before it. So, if you start with 0, the next number will be 1, followed by 1, followed by 2, followed by 3 and so on. As you can...

Convert distance within the US customary system using ratio reasoning.

In this video, the teacher explains how to simplify radical expressions without using an area model. Learn how to factor to break down the radicals into their prime factors, and then simplify the expression by finding pairs or triples of...

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

This video provides an introduction to ratios and explains what they are and how to write and simplify them. The presenter uses real-world examples to illustrate how ratios are used in everyday life, such as in baking and mixing cement....

👉 In this video, you will learn how to solve a word problem using proportions. To do this we will identify our unknowns as well as our ratio of terms. We will then proceed to set up a proportion and solve it.

It defines buffer solutions and its preparation.

It explains the working of SONAR.

An overview of the types of numbers.

In this video, the teacher explains how to calculate the measurements for a scale model of the Parthenon using ratios and proportions. The lesson covers the concepts of ratios, proportions, corresponding sides in similar triangles, and...

Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.

👉 Learn how to solve problems using percents. When solving problems with percents we will either convert the percents to decimal form or use proportions to solve. We will look to solve for the percent of change, the original price,...
