the ratio of males to females in a college class is 2:6. If there are 72 students in the class, how many are male?
m = male
Cross multiply and solve for m.
2/8 = m/72
18?
Right.
Thank you so much Ms. Sue! You have been so much help :)
You're very welcome.
But after this, please use the same name for your posts.
To find the number of males in the college class, we need to determine how many parts are represented by each ratio unit and then multiply that number by the given ratio.
The given ratio is 2:6, which means there are 2 parts representing males and 6 parts representing females.
To find the value of each part, we divide the total number of parts (2 + 6 = 8) by the total number of students in the class (72):
72 / 8 = 9
Each part represents 9 students.
Now, we can determine the number of males by multiplying the number of parts representing males (2) by the value of each part (9):
2 * 9 = 18
Therefore, there are 18 male students in the class.
