Which best describe the meaning of the statement
" if a, then b"?

In general, a mathematical statement consists of two parts: the hypothesis or assumptions, and the conclusion. In your case, "If A, then B" or "A implies B" or "A ⇒ B". The conditions that make up "A" are the assumptions we make, and the conditions that make up "B" are the conclusion. Statement "If A, then B" is called logical implication.

For the "A ⇒ B" there are such possibilities:

1. A and B are both true, then "A ⇒ B" is also true;

2. A true, B false, then "A ⇒ B" is false;

3. A false, B true, then "A ⇒ B" is true;

4. A and B both false, then "A ⇒ B" is true.

A mathematical statement generally constitutes of two parts :

In the given statement, "If A, then B" means "A implies B".

Here the conditions that comes under A are the assumptions and the conditions that comes under "B" are the conclusion.

The given Statement "If A, then B" is called logical implication.

The possibilities for the given statement : "If A then B" are :

1. If both A and B are true,

then "A ⇒ B" is also true;

2. If A is true and B is false,

then "A ⇒ B" is false;

3. If A is false but B is true,

then "A ⇒ B" is true;

4. If A and B both are false,

then "A ⇒ B" is true

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
