    You cancel factors that are common to the numerator and the denominator.

    Can you help me w/ this? Add the following fractions. Be sure to find the common denominator (multiple) and then simplify

    In the first equation (3/16) the only thing to do is to carry out numerical division. So you will end up with 0.1875

    No he's got to add two fractions by finding a common denominator, then adding the numerators of the equivalent fractions. Not convert to decimal...

    Correct. Now, we are looking for common multiplies of those two numbers. So what are the multiples of 16?

    Ok the first thing you have to do is to divide the two numbers (16 and 48) in the denominator by 2. If they both are divisible by 2, then you save this number 2. Next, you have to devide the remaining of the last divison by two again. the new two numbers are 8 and 26. If both numbers are divisible by 2 again. You save this number (2) again. 16 48 * .---------- 8 26 * 2 This number is saved 4 13 * 2 This number is saved too * Of course the remaining numbers are not divisible by 2 nor 3, and so on. This means the the common denominator is 2*2 =4 Question? Remember this is the first step

    48 is the smallest multiple that 16 and 48 have in common.

    So what do I do w/ the 48?

  43. polpak

    So 16 * 3 = 48. Now we need to make both of the fractions have that denominator. Since 5/48 already has that for the denominator we don't need to change it.

  44. polpak

    So you can just write 5/48 on the next column over. But to make 3/16 have a denominator of 48, we need to multiply the bottom by 3. In order to do that and keep the ratio the same, we must also multiply the top by 3.

    Err. \[\frac{3}{16} * \frac{3}{3}\]

    We need to change the denominator of the 3/16 so it is also using our lowest common denominator.

    We can multiply any number by 1 without changing it. Since 3/3 = 1, we can multiply our fraction by 3/3 and it will still have the same value.

  50. polpak

    But now it will have 48 for a denominator.

    You can divide both numerator and denominator by the greatest common divisor of the two. ;-)
