Answer/Explanation:
Note the following rule:
1. If number 5, 6, 7, 8, or 9 comes after the number you're rounding, ROUND UP.
2. If 0, 1, 2, 3, or 4 comes after the number you're rounding, ROUND DOWN.
Now let's round the following numbers given to us:
Reina: 49.71 m
✔️Round to nearest whole number:
7 comes after the nearest whole number which is after 49, therefore, we would ROUND UP.
Thus,
49.71 ≈ 50 (to nearest whole number).
✔️Round to nearest tenth:
The tenth is "7". 1 comes after 7, therefore, we would ROUND DOWN.
Thus,
49.71 ≈ 49.7 (to nearest tenth).
Heart: 44.57 m
✔️Round to nearest whole number:
5 comes after the nearest whole number which is after 44, therefore, we would ROUND UP.
Thus,
44.57 ≈ 45 (to nearest whole number).
✔️Round to nearest tenth:
The tenth is "5". 7 comes after 5, therefore, we would ROUND UP.
Thus,
44.57 ≈ 44.6 (to nearest tenth).
Princess: 37.42 m
✔️Round to nearest whole number:
4 comes after the nearest whole number which is after 37, therefore, we would ROUND DOWN.
Thus,
37.42 ≈ 37 (to nearest whole number).
✔️Round to nearest tenth:
The tenth is "4". 2 comes after 4, therefore, we would ROUND DOWN.
Thus,
37.42 ≈ 37.4 (to nearest tenth).
Same applies to the rest.
Marcia: 27.14 m
✔️27.14 ≈ 27 (nearest whole number)
✔️27.14 ≈ 27.1 (nearest tenth)
Pong: 26.34 m
✔️26.34 ≈ 26 (nearest whole number)
✔️26.34 ≈ 26.3 (nearest tenth)
