Last question pls help

60%

Step-by-step explanation:

So, lets look at the table.

We need to find the male percentage of sophomore students.

We need to look at the total sophomore student count first.

Well, it doesnt say. But lets just add the female and male count together.

4+6

=

10

Ok, so we know our total is 10

Now, lets look at the amount of males specificly.

This is 6.

So we also know that there are a total of 6 m,ale sophomore students.

Now, lets divide the amount of male sophmore students by the total sophmore students:

6/10

=

0.6

Well, to calculate percentage, just multiuply the decimal by 100.

100x0.6

=

60

So we know our percentage is 60%

Hope this helps! :)
