Interpretation: Number of quarters that must be lined in a row to reach 1 meter length needs to be explained.
Concept Introduction: In case of converting one unit to another choose a conversion factor, which cancels the units and omits the units in the result. Conversion factors are the ratios of two parts of the unity report which compares two units.

Answer to Problem 20A
Number of quarters that must be lined in a row to reach 1 meter length is
Explanation of Solution
Number of quarters that must be lined in a row to meeting 1 meter length is calculated as follows:
In case of conversion of m to cm the conversion factor is
Number of quarters that must be lined in a row to reach a length of 1 meter is
