Question

The length of cell A is 6 x 10^-6m. The length of cell B is 0.0000003m. What is the ratio of cell A’s length to cell B’s length? Are the numbers expressed in scientific notation or in standard form?

Answer 1

A:B=20:1

A is originally in scientific notation.

B is in standard form originally.

Explanation:

A in standard notation is 6/1000000=0.000006.

B is 0.0000003.

So A = 20 times B.

SO A:B= 20:1

A is originally in scientific notation.

B is in standard form originally.
