Article: Figuring out the average of something is simple. It means that you take every single number in the list. Write them down or put them in a spreadsheet. That means that you add them all up for a grand total. Let's say you have 5 ages: 31, 30, 26, 21, 10. The total or sum of those numbers is 118. That's the average. Using the above example, you would divide 118 (the sum of all the ages) by 5 (the number of ages in the list). The average age is 23.6. This works for much larger number sets too. For example, let's say you wanted to find the average age of people in a club. Let's say there were 100 members in the club. You would need the exact ages of each club member. You would add those ages together to get a sum. Then, you would divide that sum by the number 100. That's the average age of members in the club. It's no different when calculating average for other types of numbers that aren't ages. Average works the same way. For example, let's say you want to know the average population of the 10 largest cities in America. You would list the population for each city. Then, you would add all of those numbers up. You would divide the sum by 10, and that's the average. There are times you might want to use a weighted average. For example, when averaging a student's grades, you might want to weigh some assignments as being worth more than others.To do this, multiply each grade by the weight. Then add those numbers together, and divide by the total number of grades
Question: What is a summary of what this article is about?
Organize all of the ages in a list. Find the sum of all of the ages on the list. Now, divide the sum you got by the number of ages in the list. Find the average of other sets of numbers.

According to the Institute of Medicine, you should be getting about 10 cups of water per day while pregnant. Each cup should be eight ounces of liquid. Inadequate water intake is the most common cause of constipation during pregnancy. Because food is moving more slowly through your body, it absorbs more water. Therefore, drinking more water can help soften your stools. One easy way to keep track is to fill up several bottles in the morning that equal the amount you need to drink throughout the day. That way, you can easily keep track of how much you've drank. You can also fill up one big container with the amount you need to drink and use it to fill up your glass. For instance, fruits such as watermelon have a high water content. Similarly, vegetables such as spinach and cucumber have a lot of water. Therefore, eating more of these veggies can help increase your water intake. You don't have to get your water from just water. Liquids such as milk and juice also count. However, calories and sugar can add up quickly with these beverages (especially juice), so drink them in moderation. In addition, you can try decaffeinated herbal teas while pregnant to help with fluid intake. If you don't like drinking plain water, trying adding flavors to your water. For instance, you can add a slice of orange or lemon. You can also add a couple of slices of cucumber or even some ginger to help flavor your water. If you're having trouble remembering to drink water, try setting reminders on your phone or computer. Set one every hour or so to remind you that you need to be drinking water.
