What is a tape diagram?

Back

A tape diagram is a visual representation used to illustrate ratios and relationships between quantities. It looks like a series of connected rectangles that represent parts of a whole.

How do you use a tape diagram to solve ratio problems?

Back

To use a tape diagram for ratio problems, draw rectangles to represent each part of the ratio. Then, use the total number of parts to find the value of each part and solve for unknown quantities.

If the ratio of cats to dogs is 2:3 and there are 15 dogs, how many cats are there?

Back

10 cats (2 parts for cats and 3 parts for dogs means 2/5 of the total 15 dogs = 10 cats).

What does it mean if a tape diagram has equal-sized sections?

Back

Equal-sized sections in a tape diagram indicate that the quantities represented are in equal ratios or proportions.

If there are 24 students in a class and the tape diagram shows 3 sections for boys, how many boys are there if the ratio of boys to girls is 3:1?

Back

18 boys (3 parts for boys out of 4 total parts: 24 students / 4 parts = 6 per part; 3 parts x 6 = 18).
