I’ll use “x” as “a number”
So it’s basically asking if-
X-3=X-3
Obviously the answer is yes.
X-3 is equal to X-3.
907.5 because you multiply 181.5 x 5 which equals 908.5
Answer:
1/4
Step-by-step explanation:
So, we can create this representation of a in relation with b, since we know a is smaller than b by 1/5 of b, we can say that a is equal to 4/5 of b, right?

To invert the ratio, we need to isolate B, so we multiply both sides of the equation by 5/4

So, we have b being 1/4 bigger than a.
16 is the rational number, hope this is helpful
