Margo's soccer coach brought a large bag of watermelons to practice. The mass of the bag with all the watermelons in it was 12 kilograms.
Explain how you could use estimation to figure out how many watermelons are in the bag.
The average weight of a watermelon is about 10 kg. There are probably 1 or 2 watermelons in the bag.
Of course these could be a smaller variety of melon -- perhaps weighing only 3 or 4 kg each.
To estimate the number of watermelons in the bag, you can use the mass of the bag and make assumptions about the average weight of a watermelon. Here's a step-by-step approach:
1. Start by assuming an average weight for a watermelon. Let's say, for example, that an average watermelon weighs around 2 kilograms.
2. Divide the total mass of the bag by the assumed average weight of a watermelon. In this case, divide 12 kilograms by 2 kilograms per watermelon.
12 kg ÷ 2 kg/watermelon = 6 watermelons
So, based on this estimation, there might be around 6 watermelons in the bag.
It's important to note that this estimation is based on assumptions, and the actual number of watermelons in the bag may vary.
To estimate the number of watermelons in the bag, we can use the information that the mass of the bag with all the watermelons in it is 12 kilograms.
One way to do this is by estimating the average mass of each watermelon. You could start by finding the average mass of a watermelon, either by researching or making an educated guess based on previous experience. For example, let's say you estimate that an average watermelon weighs about 2 kilograms.
To calculate the estimated number of watermelons in the bag, you can divide the total mass of the bag (12 kilograms) by the estimated average mass of each watermelon (2 kilograms):
Estimated number of watermelons = Total mass of the bag / Estimated average mass of each watermelon
Estimated number of watermelons = 12 kilograms / 2 kilograms
Estimated number of watermelons = 6 watermelons
So, based on this estimation, there are approximately 6 watermelons in the bag. It's important to note that this is just an estimate and the actual number of watermelons in the bag could be different.
