Question

A white blood cell has a diameter of approximately 12 micrometers or 0.012 um a model represents its diameter as 24 um what ratio of model size

Answer 1

Answer:

The ratio of the model size is 1 : 2000

Explanation:

Given

Real Diameter =  0.012 um

Scale Diameter =  24 um

Required

Determine the scale ratio

The scale ratio is calculated as follows;

$Scale = \frac{Real\ Measurement}{Scale\ Measurement}$

Substitute values for real and scale measurements

$Scale = \frac{0.012\ um}{24\ um}$

Divide the numerator and the denominator by 0012um

$Scale = \frac{1}{2000}$

Represent as ratio

$Scale = 1 : 2000$

Hence, the ratio of the model size is 1 : 2000
