Lila collected the honey from 3 of her beehives. from the first hive she collected 2/3 gallon of honey. the last two hives yielded 1/4 gallon each.
a. how many gallons of honey did lila collect in all?

To solve this, you must add 2/3 + 1/4 + 1/4.
First, convert them all to have common denominators.
2/3 x 4/4= 8/12
1/4 x 3/3= 3/12
1/4 x 3/3= 3/12
Now, add them...
8/12 + 3/12 + 3/12 = 14/12 gallons.
Now, since it's an improper fraction, first lets simplify...
14/12 divided by 2/2 = 7/6
Now, convert 7/6 into a mixed number...
7/6= 1 1/6
SO, Lila collected 1 and 1/16 of a gallon in all

I HOPED THIS HELPED! :D
