Question

A scale drawing uses the scale 3 in. = 20 ft. Find the missing measure. ____in = 26 2/3 ft

Answer 1

3 in. = 20 ft
x in. = 26 2/3 ft

Cross multiply:

80 = 20x

Divide both sides by 20:

4 = x

Answer 2

Hence, the missing term is:

4

Explanation:

We are given a scale in drawing by;

`3\ in.=20\ ft.`

Now we are asked to find the missing term in the given conversion.

Let the missing term be 'x'.

Hence, we have to calculate the value of 'x'.

i.e. we are given:

`x\ in.=26(2)/(3)\ ft.`

which is equal to:

`x\ in.=(80)/(3)\ ft.`

Since,

`3\ in.=20\ ft.`

This means that:

`1\ ft.=(3)/(20)\ in.`

Hence,

`(80)/(3)\ ft.=(3)/(20)* (80)/(3)\ in.\\\\(80)/(3)\ ft.=4\ in.`

Hence, the value of the x is:

4
