20: 1, 2, 4, 5, 20 the answer is 20
-0.75-(-2/5) + 0.4 + (-3/4)
Simplify it :-)

The answer would be "B". A seems to be a "hypothesis". C is an axiom and D is a definition. I hope this was helpful.
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.
