Solving Percent Word Problems Effectively

The video tutorial from MooMooMath and Science covers solving percent word problems using a proportion method. It includes examples such as Martin's math problem, the Braves' game wins, and Mr. B's class attendance. The method involves setting up a proportion with part over whole equals percent over 100, cross-multiplying, and solving for the unknown. The video emphasizes understanding the concept and encourages kindness.

Martin was given 10 math problems and answered 7. What percentage of the problems does he have left to solve?

• 40%

• 70%

• 30%

• 50%

If Martin answered 7 out of 10 math problems, what percentage did he complete?

• 70%

• 40%

• 50%

• 30%

The Braves won 60% of their 150 games. How many games did they win?

• 100

• 90

If the Braves played 150 games and won 90, what percentage of games did they win?

• 80%

• 70%

• 60%

• 50%

In Mr. B's class of 32 students, 28 were present. What percentage of students were present?

• 87.5%

• 75%

• 80%

• 85%

If 28 out of 32 students were present in Mr. B's class, what percentage were absent?

• 15%

• 12.5%

• 25%

• 20%

What is the formula used to solve percent word problems in the video?

• Whole over part equals percent over 100

• Part over whole equals percent over 100

• Part over percent equals whole over 100

• Whole over percent equals part over 100

What is the first step in solving a percent word problem according to the video?

• Subtract from 100

• Set up a proportion

• Cross multiply

• Divide both sides by 100
