Question

Write an expression for the number of yards in f feet.

Answer 1

1 yd = 3 ft

y - the number of yards

`y=3\cdot f\to y=3f`

Answer 2

For this case, we have by definition:

`1 \ yard = 3\ feet`

We then define the following variables:

• y: number of yards
• f: number of feet

We write the function that relates both variables:

`y = 3f`

Answer:

an expression for the number of yards in f feet is:

`y = 3f`
