You have 3 pairs of jars that are all the same size. The 2 jars in each pair need to have a different amount of sand. Use fractions to decide how full to make each jar

Answer 1

Hi Leah,

Step One: "Three pairs of jars" means that there are 6 jars in total.

Pair 1: FULL JAR and half full jar

Pair 2: FULL JAR and half full jar

Pair 3: FULL JAR and half full jar

We're labeling the jars as FULL and half full because the question states that each needs "a different amount of sand"

Step 2: Create Let Statements. Let F=the amount of sand needed to fill one jar. Let F/2 =the amount of same needed to fill half of a jar.

Step 3: Create an expression. We know that there are three FULL JARS and three half full jars. Let's abbreviate FULL JAR as F and half full jar as H. This translates to our final expression:

3F+3(F/2)
