Question

A Science Class Is Studying FingerPrints. The Samples Need To Be Magnified 80 Times In Order For Students To Identify The Key Features.

If An Actual Sample Is 18 Millimeters Long , How Many CM Is The Magnified Image

Answer 1

first you have to know how many millimeters is 1 cm, since millimeters is a smaller unit, and this way is easier.
1 Centimeter = 10 millimeters

Answer 2

the magnified image = 80 x the original size
= 80 x 18 = 1440 mm = 144 cm = 1.44 m

Answer 3

So Its 144

Answer 4

let actual sample be x= 18mm
80 times magnified sample is = 80x = 18x80 mm

Answer 5

1 millimeter = 0.1 cm so 0.1 times 18

Answer 6

1.8

Answer 7

1.8 x 80 = 144cm
