ANSWER: 7
EXPLANATION/EQUATION:
40 ÷ 6 = 6.666...
≈ 7
After you divide, you are left with 6.666... When rounding to the nearest whole number, the number needs to be rounded based on the tenth; in this case, the tenth is represented by a 6. 6 is closer to 10 than 1, so you round up. Therefore, the answer is 7.
