How to set up and solve as a proportion different problems with percents, 8% of 13

The video tutorial explains how to solve percentage problems by understanding the concept of 'part over whole' and using proportions. It guides students through setting up equations by identifying parts, wholes, and percentages. The tutorial also demonstrates solving these equations using cross multiplication, with examples to clarify the process.

What is the basic proportion used to solve percentage problems?

• Part over whole equals percent over 100%

• Whole over part equals percent over 100%

• Part over percent equals whole over 100%

• Whole over percent equals part over 100%

In a percentage problem, if you have $50 and want to find 10% of it, what is the whole?

• $5

• $50

• 10%

• $10

When setting up a percentage problem, what do you need to identify?

• Neither the part nor the whole

• Both the part and the whole

• Only the part

• Only the whole

What is the first step in solving a percentage problem using cross-multiplication?

• Add the part and whole

• Multiply the part by 100

• Divide the whole by the part

• Simplify the fraction

How do you find the percentage when given a part and a whole?

• Subtract the part from the whole

• Add the part and the whole

• Multiply the part by the whole

• Divide the part by the whole and multiply by 100
