Explanation

Hi today I am going to show you how to add and subtract fractions

Step 1-if the to fractions don't have the same denominator you have to find the least common multiple

Step 2- so let's say we have 1/3+1/2 the least common multiple is is 6 so the denominator is 6

Step 3- so we had to multiple 3x2 and 2x3 to get to 6 as the denominator so we have to do the same thing to the numerator.

step 4 so we do 1x3 and 1x2 and that equals 2 and 3 so then you just add 3/6+92/6 equals 5/6 and you do the exact same steps for subtractions but you just subtract at the end

HI now i am going to show you how to multiply fractions

step1 line up the fractions 1/2x1/3=

step 2 then just multiply across

step 3 1/6

Hi today am going to show you how to divide fractons
