Step-by-step explanation:
We are asked to find the difference which means we will be using subtraction.
We are given two numbers to use (Houston to Dallas) &
(San Antonio to Houston).
To be able to subtract, we need to have the same denominator on both fractions, which we can do by multiplying 1/3 by 4
now we can subtract the numbers and simplify!
I'll give you a hint. <u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtracting.</em></u>
First you had to calculate with parenthesis first.
Then you add and subtract from left to right.
