Ned caught 1/3 pound of fish. sarah caught 5/12 pound of fish. jesse caught 1/6 pound of fish. how many in total did they catch?

Ok so since the largest denominator is 12 we want to get the other denominators the same so it is easier to add together. Multiply 3 by 4 to get a denominator, then multiply 1 by 4 and you'll get 4/12. Then multiply 6 by 2 and then 1 by 2 and you'll get 2/12. Add all 3 of the fractions to get 11/12 pounds of fish. Hope this helps!

They caught: 11/12 pounds of fish
First you need to change them to a same common denominator. Since 3 and 6 already go into 12, you just have to change 1/3 and 1/6 to a denominator with 12.
First you need to change 1/3 to 4/12. By doing that, you do: 1/3x4/4=4/12.
You then have to change 1/6 to 2/12. By doing that, you do: 1/6x2/2=2/12.
Then you just add up all the fractions and simplify: 4/12+2/12+5/12=11/12.
You can't simplify 11/12 any further so you're answer would be:
They caught 11/12 pounds of fish in total.
Hope this helps! :D
