Question

Muna is making a scale drawing of a gecko. The gecko is 1:2 inch wide and 5 inches long. she decides to make her drawing of the gecko 1 inch wide. How long will the drawing be ? show your work

Answer 1

L= 0.83 in

Explanation:

Width= 1.2 in when length = 1 in

Required

Determine the length when width = 1 in

First, we need to determine the ratio

Ratio =
`(Width)/(Length)`

Ratio =
`(1.2)/(1)`

Ratio = 1.2 ---(1)

Let the required length be represented with L

So:

Ratio =
`(Width)/(Length)`

Ratio =
`(1)/(L)` ---(2)

Equate (1) and (2)

`(1)/(L)` = 1.2

Multiply through by 1.2

L *
`(1)/(L)` = 1.2 * L

1 = 1.2 * L

Divide through by 1.2

L =
`(1)/(1.2)`

L = 0.83 in (Approximated)
