Question

The tape diagram represents an equation.
2 tape diagrams that represent the same length. The top tape diagram has 1 part, which is 16 units. The bottom tape diagram has 4 equal parts. All 4 of the parts are y units.
\[16\]
\[y\]
\[y\]
\[y\]
\[y\]
Write an equation to represent the tape diagram.
Choose 1 answer:
A

\[16=\dfrac{y}{4}\]
B
\[16=4y\]
Find the value of
\[y\] that makes the equation true.
\[y=\]

Answer 1

The bottom bar is 4 parts of length y, so 16 = y + y + y + y = 4y. (Choice B.)
Solve: 16 = 4y ⇒ y = 16/4 = 4.
