#### Explanation:

#"reduce the fraction by dividing the numerator/denominator"#

#"by the "color(blue)"highest common factor"#

#"in this case the highest common factor is 14"#

#rArr84/98=(84-:color(red)(14))/(98-:color(red)(14))=6/7#

#"this is often expressed using "color(blue)"cancelling"#

#rArrcancel(84)^6/cancel(98)^7=6/7#

#"if you do not see that 14 is the highest common factor"#

#"then begin by using smaller common factors"#

#"2 is a common factor of both numbers"#

#rArrcancel(84)^(42)/cancel(98)^(49)=42/49#

#"now repeat using the common factor of 7"#

#rArrcancel(42)^6/cancel(49)^7=6/7larrcolor(red)"in simplest form"#

#"A fraction is in "color(red)"simplest form"" when no other"#

#"factor but 1 divides into the numerator/denominator"#
