    Fractions are just glorified division problems. What would you like to know about them?

    like lets just say 15/18?

    Ok, well in this case they probably are just asking for you to simplify the fraction. 3/4 is the same as 9/12, however, 9/12 is not its simplest form. Likewise, 15/18 can be reduced into simpler numbers. Are you able to reduce 15/18 into its lowest terms?

    All you need to do is find a common factor of 15 and 18 and then divide both numbers by that factor.

    If we look at 9/12, we notice that 9 and 12 both have a common factor in the number 3. Let's divide 9 by 3 = 3. Let's divide 12 by 3 = 4. Lo and behold, we now have 3/4. 3 and 4 share no common factors, therefore this is the most simplified form of 9/12.

    I know from my multiplication tables that 9 is equal to 3x3 and that 12 is equal to 3x4. Notice how both of them have one 3 in common. 3 is then my common factor. Knowing that both have a factor of 3, I can divide both 9 and 12 by three to reduce them into smaller numbers.

    so dont matter wat number we have to find the number that fits both to reduce right? and it all have multiplication to find the number that fits?

    That is correct. You will be able to simplify faster if you know your multiplication tables well enough to find the Greatest Common Factor right off of the bat. However, some numbers can be tricky if they are large enough. Just remember, if both numbers are even, they can always be simplified, both can be divided by 2.
