Question

The rise and span for a roof is the ratio of the rise to the half-span. If the rise is 8 feet and the span is 30 feet,what is the pitch in simplest form?

Answer 1

8 feet to 15 feet or
`(8)/(15)`.

Explanation:

We know that pitch is is the ratio of the rise to the half-span.

It is given that, the rise is 8 feet and the span is 30 feet.

`\text{Half of span}=(30)/(2)=15`

We need to find the pitch in simplest form.

`Pitch=\frac{\text{Rise}}{\text{Half-span}}`

`Pitch=(8)/(15)`

Therefore, the pitch in simplest form is 8 feet to 15 feet or
`(8)/(15)`.
