Answer:
(running water, city water, town water, municipal water, sink water, etc.) is water supplied to a tap (valve). Its uses include drinking, washing, cooking, and the flushing of toilets. Indoor tap water is distributed through "indoor plumbing", which has existed since antiquity but was available to very few people until the second half of the 19th century when it began to spread in popularity in what are now developed countries. Tap water became common in many regions during the 20th century, and is now lacking mainly among people in poverty, especially on Indian Reservations in the US and in developing countries.
1. 3.81 = 3.8 because 8 is in the tenths place and you rounded it. 1 is less than 5 so the number stays the same.
2. 72.27 = 72.3 because 2 was in the tenths place and you rounded it by 7. 7 is more than 5 so the number changes to 3.
The number beside the number you want to round on the left must be equal or more than 5.
