Answer:
They most have common denominators.
Step-by-step explanation:
Let the following two rational expressions:
where p,a,q, b are integers, a and b the denominators are not 0, i.e.
We can add rational expressions only if their denominator is same.
That is why we find LCD to be .
Then,

So, the correct answer is the last option that we can sum rational expressions if they have common denominator.
Answer:
option (A) 62 miles
Step-by-step explanation:
Data provided in the question:
Ratio on the left = 434 miles : 14 gallons
ratio on the right = ?? : 2 gallons
Now,
The ratio on the both sides are equal
let the unknown value in the ratio be 'x'
Now, the ratio a : b can also be represented as
therefore,
434 miles : 14 gallons = x : 2 gallons
or
⇒ =
or
⇒ x =
or
⇒ x = 62 miles
Hence,
the correct answer is option (A) 62 miles
