For every girl taking classes at the martial arts school, there are 3 boys who are taking classes at the school. If there are 236 students taking classes, write and solve a proportion to predict the number of boys taking classes at the school.
the answer is 177
3/4 = x/236
Cross multiply and solve for x.
3/4=x/236 cross multiply 3 and 236 and drop down the 4and x to get 4x=708 and divide 4/4 and 708/4 and get 177
Thanx! I was doing this on my homework, and I'm so glad I was able to find this!! :D
The answer is 177
3/4. ?/236
4•59=236
3•59=177
177 is the answer
