Sixty students voted in a class president. 30% of the students voted for Shawn and 70% of the students voted for Jane. How many
JulsSmile [24]
There are 60 students. The winner got 70% of the 60 students votes. Let's work this one out to get the answer.

First, you need to figure out what 70% of 60 is, by using this equation.
60 x .70 = 42.
Now that you know the answer is 42, you now know that 70 percent of 60 is 42.

So, the class president got 42 winning votes!






Hope I could help!
