So if boys is 6 and girls is 15 it would be 6/15, but that can be simplified to 2/5.
Answer:

Step-by-step explanation:
If two lines are perpendicular, they create 4 90° angles. Meaning, in this case, that m<DBC = 90 and m<DBA = 90.
We're given that m<DBE = 2x - 1 and that m<CBE = 5x - 42.
The sum of angles DBE and CBE = m<DBC = 90°
We can add the two angles and set it equal to 90 to find x

3x - 8 = -2 |subtract 10 from both sides
3x - 18 = -12 |divide both sides by 3
x - 6 = -4
