If you change 1/4 so that the denominators of both fractions are the same by mutiplying 4x3 for the bottom and 3x1 for the top and then add 5/12 and 3/12 to get 8/12 and then for it to be a whole number, you need 4/12 to complete the whole which is the fraction of children at the bleachers at the basketball game (4/12) .
Answer:

Step-by-step explanation:

Is there supposed to be a picture? I don’t see one.
AB = QR
BC = PR
CR = PQ
<A = <Q = 60
<B = <R = 90
<C = <P = 30
•Slope is defined as "rise over run."
•Make sure that the line is straight. You can't find the slope of a line that isn't straight.
•Coordinates are the xand y points written as (x, y). It doesn't matter which points you pick, as long as they're different points on the same line.
•It doesn't matter which one you pick, as long as it stays the same throughout the calculation. The dominant coordinates will be x1 and y1. The other coordinates will be x2 and y2.
•Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
•Subtract the two y-coordinates from one another.
•Divide the y-coordinate's result with the x-coordinate's result. Reduce the number if at all possible.
