1:3 is the ratio to boys and girls. I know that 1/4 must be girls. 3/4 will be boys.
Divide 236 by 4.
236/4= 59
Multiply that by 3.
59*3= 177
177 of the students are boys.
I hope this helps!

because 5x15=75, 8x3=24, 75-24=51
A point in the form of (0, number) is the y - intercept. That's because there is movement in the x -direction and the point is plotted on the y -axis. Our number in the ordered pair is the y-intercept - in this case, 10.
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept. We are told the slope is 9 and we found the y-intercept, 10. 9 goes in for m, 10 goes in for b.
Thus the line (in slope intercept form) is y = 9x + 10.
Add 10 to 894.
894 + 10 = 904
