解析
Two approaches you could use to solve this problem are:
1: Translate from words to algebra.
2: Determine a mathematical relationship between the two quantities.
Approach 1: You can represent the least of the three consecutive integers by x, and then the three integers would be represented by x, x + 1, and x + 2. It is given that the sum of the three integers is -84, so x +(x + 1)+(x + 2)= -84. You can solve this equation for x as follows.
x +(x+1)+(x + 2)= -84
3x + 3 = -84
3x = -87
x = -29
Since the least of the three integers, -29, is less than -28, the correct answer is Choice B.
Approach 2: You could ask yourself what would happen if the least of the three consecutive integers was -28. The three consecutive integers would then be -28, -27, and -26, and their sum would be -81. But you were given that the sum of the three consecutive integers is -84, which is less than -81. Therefore, -28 is greater than the least of the three consecutive integers, and the correct answer is Choice B.
