Question

A particular plant root grows 3.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters).

Answer 1

Type in the given rate:  3.5 inches per month.  Next, realize you must convert "inches" to "cm," remembering that 1 inch = 2.54 cm (approximately).  Make a conversion factor out of "1 inch = 2.54 cm" as follows:  1 = 2.54 cm / 1 inch.
Multiply "3.5 inches per month" by this factor 2.54 cm / 1 inch.  Note that "inches" will then cancel out, and your measurement will be in cm / month.

Answer 2

It's very easy!!! 3.5*2.54=8.89 cm
