- A.
9 cm
- B.

Correct Answer
C. 11 cmExplanation
The given question is asking for the length of a pencil when rounded to the nearest centimeter. The length of the pencil is stated to be 10 cm plus 9 mm. To convert the 9 mm to cm, we divide it by 10, which equals 0.9 cm. Adding this to the 10 cm, we get a total length of 10.9 cm. When rounding to the nearest centimeter, 10.9 cm would be rounded up to 11 cm. Therefore, the correct answer is 11 cm.Rate this question:

- A.
13 cm
- B.
14 cm
- C.
15 cm
- D.
16 cm
Correct Answer
C. 15 cmExplanation
Tasya memiliki pita sepanjang 14 cm lebih 8 mm. Kita perlu mengkonversi 8 mm ke dalam cm terlebih dahulu. Karena 10 mm = 1 cm, maka 8 mm = 0,8 cm. Jadi, panjang pita Tasya adalah 14 cm + 0,8 cm = 14,8 cm. Ketika dibulatkan ke xm terdekat, angka desimal 0,8 akan bulat ke atas menjadi 1. Jadi, panjang pita Tasya yang dibulatkan adalah 15 cm.Rate this question:
