The next part may be tricky for some students. Ask them, "If you had twice as many M&Ms on your desk, but the same ratio of red to blue, how many blue M&Ms would you have?" Allow them to take out as many more M&Ms as they need to solve the problem. Now the students can be shown that this can be expressed as a proportion, and can be solved using cross-multiplication: 4/5 = x/10. It is essential to show the students that no matter which individual number is unknown, cross-multiplication can be used to solve it.
Finally, return to the original 4/4...
Ask the students what percent of the M&Ms are red, but give them the aforementioned definition of a percent, and write the following on the board: 4/4 = x/100. Show them how to work the cross-multiplication, and then write "percent" after your answer. Tell them this x/100 figure can be used to solve virtually any percentage problem they will come across. Next, prove this is the case by brining out the blue M&M again: 4/5 = x/100. x = 80-percent. The students should also be shown that the same magical result can be arrived at using twice as many M&Ms.

technology are often widespread and have the possibility to change the way humankind operates within itself. Technology paves the way for new technology creating a system of seemingly eternal growth and unlimited potential. It is therefore important and worthwhile to investigate and highlight certain aspects of the ways technology impacts different environments.

Human trafficking is often thought of as a problem indigenous only to developing nations. However, the phenomenon is pervasive internationally, including in the United States. Examples of human enslavement in the U.S. that have recently been exposed by the media and law enforcement have been found in the fields of domestic service, prostitution, farm labor, factories, and mining (Bales & Soodalter 2007). "Trafficking supplies human beings for prostitution, sweatshop labor,
