Question

If David and jake each looked at a strand of their hair under a microscope measured the diameter jake strand was 0.005 cm in the diameter David strand was 0.0012 cm in diameter

Answer 1

Answer:

$=\frac{0.005}{0.0012}$

= 4.17

$\approx 4$

Jake's strand represents 4 times David's strand.

Step-by-step explanation:

* microscope measured the diameter jake strand was 0.005 cm in the diameter

* David strand was 0.0012 cm in diameter

To find the ratio , we will have  to divide them

k=0.005cm and

d=0.0012cm

by dividing we get,

$=\frac{0.005}{0.0012}$

= 4.17

$\approx 4$

Therefore, Jake's strand represents 4 times David's strand.

Answer 2

Answer:

Jake's strand represents 4 times David's strand.

Step-by-step explanation:

To find the ratio between these diameters, we just need to divide them

$k=0.005cm$ and $d=0.0012cm$

If we divide

$\frac{k}{d}=\frac{0.005}{0.0012} \approx 4$

Therefore, Jake's strand represents 4 times David's strand.
