For every girl taking a material arts class there are 3 boys taking the same class if there are 236 students at the school predict how many of them are boys

Trying to get 3:1

Divide 236 by four=59

Then times 59 by 3

The ratio now is 177:59

3:1

Let x be the number of girls and y the number of boys

1st equation: x + y = 236

But for each y (boy), there 3x (girls)

2nd equation: y = 3x

Now solve:

|x + y = 236

| y = 3x

|x + y = 236

| - 3x + y = 0

You'll find x (girls) = 59 and y (boys) = 177
