Adding and subtracting unlike fractions

Step-by-step explanation: find the lest common multiple is the sighs are the same you add is the sighs are different you subtract

Step-by-step explanation:

so the first thing you do is you find the biggest number in both of the bottom numbers and then you do the smallest number and put a line next to the smallest number and then you multiple it and see how much it goes into the biggest number and then whatever you had to multiple the smallest number to the biggest you just do the same for the top of the fraction and then add or subtract straight through and then if you have a whole number and you need to borrow from the fraction you just take away 1 and then you double the 1,2,3,4,5,6,7,8,9 to 11,12,13,14,15,16,17,18,19 and then you can do the whole number just like subtracting and then you should have a whole number hopefully and then you are done.

and by the way i do not know multiplying and dividing fractions with or without whole number so i will learn and tell you when i do learn

Hope all this helps.
