A tape diagram, also known as a bar model, is a pictorial representation of ratios. In mathematics education, it is used to solve word problems.[1] So lets do this problem that has been given to us by teachers all around. A boy has won 15 games. If for every 3 games that he wins, he loses 2, how many games has the little boy lost?onomatopoeia once you get your phone number call me when you get out of the shower please come to see me today and tomorrow night and my mother is going out tomorrow come over tomorrow ExampleA math problem reads: A boy has won 15 games. His ratio for him is 3:2. The tape diagram would look something like this:
Using the above diagram, it can be concluded that the boy has lost 10 playing times.{{Empty section|date=January 2016}} How does the tape diagram workThe tape diagram works by showing different ratios. In the example before it shows how a boy has won 15 games. So if his win to loss ratio is 3:2 it would look like this. How many games has he lost?(3x5) Now how did you get those three 5s you ask.
So the answer to how many games did he lose is 10. Because 5+5=10 References1. ^{{cite book |authors=Lisa Watts-Lawton and Colleen Sheeron |title=Eureka Math Curriculum Guide: A Story of Units, Grade 2 yes |url=https://books.google.com/books?id=r5IvCgAAQBAJ&pg=PA128 |year=2015 |publisher=Wiley |isbn=978-1-118-81261-7 |page=128 }}
