Naeem weighs different salad takeout containers. The containers respectively weigh 4.5 ounces, 5.01 ounces, 5.3 ounces, 4.75 ounces, and 4.9 ounces. Which is the best whole number estimate of how much all the containers weigh together?

Question

22 ounces
24.46 ounces
24.5 ounces
25 ounces

Answer 1

To find a good whole number estimate of the total weight of the salad takeout containers, we can round each of the weights to the nearest whole number and then sum them up.

Here are the weights rounded to the nearest whole number:

• 4.5 ounces ≈ 5 ounces
• 5.01 ounces ≈ 5 ounces
• 5.3 ounces ≈ 5 ounces
• 4.75 ounces ≈ 5 ounces
• 4.9 ounces ≈ 5 ounces

Now, we can add these rounded weights together:

5 + 5 + 5 + 5 + 5 = 25 ounces

So, the best whole number estimate of how much all the containers weigh together is 25 ounces.
