Over the weekend, nolan drank 1/6 quart of orange juice, and andrea drank 3/4 quart of orange juice. how many quarts did they drink together?

They drank 11/12 all together.

Step-by-step explanation:

Set it up as:

1         3

--   +   --

6        4

Find the common denominator between 4 and 6:

4: 4,8,12

6: 6,12

The common denominator is 12

Now multiply the denominators to get 12 then multiply the numerator by the same number:

6x2=12

1/2=2

4x3=12

3x3=9

The new fractions are:

2         9       11

--    +   --  =   ---

12       12       12

They drank 11/12 quarts together.

Hope this helps! :)
