The candy is in jars.
The jars are all the same size,
all the jars are filled to the top.

List quantities (numbers) and say what they are in the terms given.
When reading a problem such as this, or a scenario, we would want to want to write down the quanitities mentioned, and be specific to what. I will write down 3/4 of a jar. Also, I would think of a the jar. One jar would be a whole jar. But she doesn't want one, she wants less. She wants only a portion, she wants threefourths.
But also, in the realworld, we speak a little differently. Jenny doesn't actually want the jar at all, she wants the jellybeans inside, and is referencing the jar for its volume, what it can hold. So, for simplicity sake, we first write down exactly what quantities are in the terms that are given.

"I will have 2/3 of the jar of M&M's please"

+ 2/3 JAR
_________
= HOW MANY JARS?

Change to an equivalent fraction by
finding a common denominator
3/4 has a numerator of 3, a denominator of 4.
4 x 1=4, 4 x 2 = 8, 4 x 3 = 12, 4 x 4 = 16
2/3 has a numerator of 2, a denominator of 3.
3 x 1 =3, 3 x 2 = 6, 3 x 3 = 9, 3 x 4 = 12
THE Lowest COMMON DENOMINATOR is: 12

Convert your fraction to a common equivalent
3/4 = 9/12
2/3= 8/12

ADD 9/12+8/12= 17/12
17/12 is an improper fraction
OR 1 5/12 JAR
is the mixed number form


The threefourths jar of jelly beans and the twothirds jar of M&M's will equate to one and fivetwelfths jar of candy in total.

Another way to express this:
3/4 + 2/3 =9/12 + 8/12
9/12 + 8/12 = 17/12
17/12 = 1 5/12
