Final answer:
To find which numbers are closest to -34 and -12, compare their values on the number line. Option c) -40 is closest to -34, while option b) -18 is closest to -12.
Step-by-step explanation:
The question asks which numbers are closest to -34 and -12 on the number line from the options provided.
To determine which numbers are closest to -34, compare the values that are less than -34 and greater than -34. Option c) -40 is less than -34 and is closer on the number line than option a) -28, which is farther in the positive direction.
For the number closest to -12, compare the values less than and greater than -12. Here, option b) -18 is the closest as it is less than -12 but closer on the number line than d) -8, which is farther in the positive direction.
