3 buses to 11 cars is the ratio
The solution to the ordered pair (3,15) is the equation y = 5x, which is letter A. This is found by substituting the value of the x into the equation and solving for y. The equation y = 5x satisfies the ordered pair (3,15) because if you substitute x with 3, the equation becomes y = 5(3) which is 15.
First, you need to find the common denominator:
1/2=3/6
Then you need to add the 2 fractions:
3/6 + 2/6=5/6
So your answer is 5/6
Answer: 
Reduce the expression, if possible, by cancelling the common factors.
