How do you find equivalent fractions with a common denominator?
You dont really, well at least in my years of knowledge
When multiplying fractions do you also multiply the denominator?
I dont know
What operations dont work for commutative property?
Subtraction, division
How do you add the top number of the unlike fraction?
You find the least common denominator and then you see how many times the denominator of the actual fraction goes into it, then you multiply that by how many times it goes into the least common denominator, then you just do it for the other fraction as well, example:6/9+3/7= The least common denominator is 56 bcuz 9 and 7 dont go into eachother, then you find how many times 9 goes into 56: which is 7 so you multiply it by 6 and you have 56/56= 1 whole, so thats the first fraction and you do the same thing to the nextYou can go to YouTube to find GREAT videos!Josh W.
How do you you add a fractions when the denominator is not the same?
ok this is like 5th grade math but you have to multiply. Say it is 1/4+3/8. You have to multiply the lower denominator which in this case is 4 to get it to 8. Which you get 4x2=8 right. Well whatever you do to the denominator you have to do to the numerator. so the numerator is 1 in the fraction of 1/4 and you get 1x2=2. So then your problem is 2/8+3/8= 5/8. If your worried that the denominator will not go into it dont because you will never get a problem like that
