Liz, jas and Sam each have a collection of marbles. The three of them pool their marbles to make a larger collection. They weigh the marbles on a postal scale. Together they have 2$6 marbles which.weigh 183 ounces. What is the average weight(unit rate) of each marble?

What is this? 2$6

Oh sorry 246 marables

183 / 246 = 0.74 ounces

To find the average weight (unit rate) of each marble, you need to divide the total weight of all the marbles by the number of marbles.

Given that Liz, Jas, and Sam have a total of 26 marbles weighing 183 ounces, the average weight of each marble can be calculated as:

Average Weight = Total Weight / Number of Marbles

Let's calculate it step by step:

1. Determine the total weight of the marbles: 183 ounces.
2. Identify the number of marbles: 26 marbles.
3. Divide the total weight by the number of marbles to get the average weight per marble:

Average Weight = 183 ounces / 26 marbles

To simplify this division, divide both the numerator and denominator by their greatest common divisor, which in this case is 13:

Average Weight = (183 ounces ÷ 13) / (26 marbles ÷ 13)
Average Weight = 14 ounces / 2 marbles

Finally, divide the numerator by the denominator:

Average Weight = 14 ounces ÷ 2 marbles

So, the average weight (unit rate) of each marble is 7 ounces.
