For every girl taking classes at a Martin martial arts school there are 3 boys who are taking classes at the school. If there a 236 students taking the classes write and solve a proportion to predict the number of boys taking classes at the school?
3/4 = x/236
Cross multiply and solve for x.
To solve this problem and predict the number of boys taking classes at the Martin martial arts school, we can set up a proportion.
Let's denote the number of girls as "g" and the number of boys as "b". We know that for every girl, there are 3 boys. Therefore, the proportion can be set up as:
g/1 = b/3
Now, we are given that the total number of students taking classes at the school is 236. Therefore, the sum of the girls and boys must equal 236:
g + b = 236
We can now solve this system of equations to find the values of g and b.
Using the first equation, we can isolate "g" by multiplying both sides by 3:
3g = b
Substituting this value of b into the second equation:
g + 3g = 236
4g = 236
g = 236/4
g = 59
Now, we know that there are 59 girls taking classes at the school. Substituting this value of g back into the equation b = 3g:
b = 3 * 59
b = 177
Thus, the predicted number of boys taking classes at the school is 177.
