The weights of five grapefruits are 7.47 ounces, 7.23 ounces, 6.46 ounces, 7.48 ounces, and 6.81 ounces. Using the clustering estimation technique, what is the approximate total weight of the grapefruits?

The weights of five grapefruits are 7.47 ounces, 7.23 ounces, 6.46 ounces, 7.48 ounces, and 6.81 ounces. Using the clustering estimation technique, what is the approximate total weight of the grapefruits?

In the clustering estimation technique, you group numbers that are close in value together and then find an approximate total. Let's group the weights of the grapefruits:

Group 1: 7.47 ounces and 7.48 ounces (total = 7.47 + 7.48) Group 2: 7.23 ounces Group 3: 6.46 ounces and 6.81 ounces (total = 6.46 + 6.81)

Now, add the totals for each group:

Group 1: 7.47 + 7.48 = 14.95 ounces Group 2: 7.23 ounces Group 3: 6.46 + 6.81 = 13.27 ounces

Now, add the totals of all the groups:

Total weight ≈ 14.95 ounces + 7.23 ounces + 13.27 ounces ≈ 35.45 ounces

So, the approximate total weight of the grapefruits using the clustering estimation technique is 35 ounces.
