Question

A student measured the length of a piece of paper and determined it to be 21.6cm using a metric measurement and 8 1/2 inches using the English measurement. What is the ratio of cm/inch using the students data.Do not give a fraction answer, calculate it to get an answer with 2 digits past the decimal

Answer 1

Explanation:

As per the measurements that are made by the student are as follows.

        21.6 cm is equivalent to 8.5 inch

Therefore, 1 cm for the given situation will be equivalent to inch as follows.

              1 cm = $\frac{8.5}{21.6}$ inch

                      = 0.393 inch

Hence, we will calculate the ratio of cm : inch as follows.

               Ratio of cm : inch = $\frac{8.5}{21.6}$

                                             = 0.39

Thus, we can conclude that the ratio of cm/inch using the students data is 0.39.
