Question

Fellow person with an easy question here :))

Answer 1

The actual wingspan of fly is 5.5cm

Step-by-step explanation:

Given,

Scale of drawing;

4mm = 1cm

Ratio of mm to cm = 4:1

Wingspan of fly in drawing = 22mm

Let,

x be the actual wingspan.

Ratio of mm to cm = 22:x

Using proportion;

Ratio of mm to cm :: Ratio of mm to cm

$4:1::22:x$

Product of extreme = Product of mean

$4*x=22*1\\4x=22$

Dividing both sides by 4

$\frac{4x}{4}=\frac{22}{4}\\x=5.5$

The actual wingspan of fly is 5.5cm
