Question 83721
7.2 is equivalent to 72/10 and 0.06 is equivalent to 6/100. So the expression becomes


{{{(72/10)/(6/100)}}}


When you divide fractions, you multiply the first fraction by the inverse of the 2nd fraction



{{{(72/10)*(100/6)}}}


{{{(72/cross(10))*(100/6)}}} Notice 100/10 reduces to 10


{{{720/6}}} Multiply


Now reduce the fraction


*[invoke reduce_fraction 720, 6]


So 

7.2/0.06 is 120
