Let's first establish the problem as the following:
= 78.32 / 0.22
First, we will make the deniminator a whole number. In order to accomplish this, we will multiply both the numerator and denominator in the fraction by 100.
= ( 78.32 × 100 ) / ( 0.22 × 100 )
= 7832 / 22
Next we will divide both the numerator and denominator by the highest common factor ( HCF ) of the two numbers in order to simplify the fraction fully.
The highest common factor of 7832 and 22 is 22.
HCF = 22
This means that we will divide both the numerstor and denominator of the fraction by 22.
or 360, so D.
