$911\div3\approx$
choose 1 answer;
a 3
b 30
c 300
d 3,000

Explanation:

Step1: Round the dividend

To estimate \( 911 \div 3 \), we first round 911 to a number that is easy to divide by 3. 911 is close to 900, since 900 is a multiple of 3. So we use 900 as the rounded dividend.

Step2: Perform the division

Now we divide the rounded number by 3: \( 900 \div 3 \). We know that \( 9 \div 3 = 3 \), so \( 900 \div 3 = 300 \) (because 900 is 9 hundreds, and dividing 9 hundreds by 3 gives 3 hundreds).

Answer:

C. 300
