The equation would be
x - 18 = collection left
X = how much was your collection before you gave your brother 13 cards
Since we don't know how big was your collection before, this would be the equation to solve it.
9 is divisible by 9, Therefore, 180 is divisible by 9 and the answer to the question, "Is 180 Divisible By 9?" is Yes.
To simplify a fraction, you must find a number both the numerator and denominator can be divided into, and divide. Say I have 4/6. Both numbers are divisible by 2, so I simplify the fraction to 2/3. As we can no longer divide, the fraction is in simplest form. Hope this helps!
