Can you put your example on here?

im also having trouble putting example im new on here .

Ok so if it is a fraction for example writ 4/3.... Is that what you don't get?
anonymous
  • anonymous
2/3 + 1/7 for example
anonymous
  • anonymous
Ok so in order to add fractions you have to find a common denominator. what is something that both 3 and 7 go into?
anonymous
  • anonymous
it can't
anonymous
  • anonymous
Well 3(7)=21 so 21 is your common denominator. Now in order to get both your denominators to be 21 you have to adjust the fractions via multiplication: 2/3 3(7)=21 2(7)=14 2/3=14/21
anonymous
  • anonymous
Now do the same thing to the other fraction so that the common denominator is 21
anonymous
  • anonymous
The easy tip that mmbuckaroos is giving you is that you can mutliply the denominators to get a common denominator. This will cause you to have to simplify later in a lot of cases, but at least you are down to an answer at that point.
anonymous
  • anonymous
i think im not getting the simplifying .
anonymous
  • anonymous
Ok well we are not to the simplifying part yet... You want to multiply both the denominators to find a common denominator but whatever you do to the bottom of a fraction you have to do the same to the top of the fraction so for the fraction 2/3... Multiply the denominator (bottom) 3*7=21 Now you have to do the same thing to the top of the fraction 2*7=14 Your fraction now looks like this: 14/21
anonymous
  • anonymous
Now do the same thing for the fraction 1/7....
anonymous
  • anonymous
Multiply the denominator (bottom) 7*3=21 Now you have to do the same thing to the top of the fraction 1*3=3 Your fraction now looks like this: 3/21
anonymous
  • anonymous
Your equation should look like this now: 14/21+3/21 Now you can simply add the numerators (top of the fraction) to get: 17/21
anonymous
  • anonymous
17/21 can not be simplified so that is your final answer
anonymous
  • anonymous
your steps are better than my instructors thanx. However i made a mistake it was 2/7+ 1/7 sorry
anonymous
  • anonymous
Ok so that is even easier! You already have a common denominator All you have to do is add the numerators
anonymous
  • anonymous
3/7 should be your answer
anonymous
  • anonymous
so it stays 3/7 cuz it cant be simplified
anonymous
  • anonymous
Yep:)

how often do u help on here u ?
anonymous
  • anonymous
Well Lately I have been on a lot trying to get some help myself... but problems like these are fun.

anonymous
  • anonymous

anonymous
  • anonymous
