what is the ratio of cell a's length to cell b's length? use pencil and paper. is it easier to find the
ratio when the numbers are expressed in scientific notation or in standard form? explain your
reasoning
the ratio of cell a's length to cell b's length is .
(type the ratio as a simplified fraction.)
