a. Rounding up becomes:
18.386 ---> 18.39
b. the pitcher’s mound to home plate is 1839 cm
Further explanation
There are general rules used in rounding numbers
-
1. Determine the rounded digit
- 2. Pay attention to the digits afterward (right). If the digit shows the numbers 0, 1, 2, 3 or 4, then the digit to be rounded is fixed, and the digit on the right is 0 all
- 3. If the digit on the right shows the numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added to one, and the digit on the right side is made all 0
In rounding the nearest hundreds number, then we see the digit in the number tens (right of the digit hundreds), if it is worth 0, 1, 2, 3 or 4, then it remains, but if it shows numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added one, and the right-hand side is 0
a. At 18.386 meters, the hundredth place is 8, and the number behind it is 6
So that number 8 to be rounded and added to one, became 9 and the digit on the right side is omitted
Rounding up becomes:
18.386 ---> 18.39
b. the distance in centimeters :
1 m = 100 cm , so
18.39 meters x 100 = 1839 cm
