Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Answer:
You just have to divide the equation by "x"'s coefficient (2).
2x/2=x
66/2=33
x=33
