Answer :
40% of 300 = 300 * 0.4 = 120 students for Jennifer
60% of 300= 300 * 0.6= 180 students for Kevin
180=120= 60 more students voted for Kevin
60% of 300= 300 * 0.6= 180 students for Kevin
180=120= 60 more students voted for Kevin
40%=4/10=4*(1/10)
60%=6/10=6*(1/10)
-----------------------------
1/10 of 300 is 30, therefore 4/10 of 300 is 120.
-------------------------------
1/10 of 300 is 30, therefore 6/10 of 300 is 180.
-----------------------------
So, 120 students voted for Jennifer and 180 students voted for Kevin therefore, Kevin received 60 more votes.
60%=6/10=6*(1/10)
-----------------------------
1/10 of 300 is 30, therefore 4/10 of 300 is 120.
-------------------------------
1/10 of 300 is 30, therefore 6/10 of 300 is 180.
-----------------------------
So, 120 students voted for Jennifer and 180 students voted for Kevin therefore, Kevin received 60 more votes.
