What number comes before 31,000?
To determine the number that comes immediately before 31,000, we need to find its predecessor.
Step 1: We start with the number 31,000.
Step 2: To find the predecessor, we subtract 1 from this number:
This calculation tells us that the number that comes before 31,000 is 30,999.
Therefore, the correct solution to the problem is .
What number follows 70,099?
Predecessor means the number that comes before (subtract 1), while successor means the number that comes after (add 1). Think of it like steps on a ladder!
When you subtract 1 from 31,000, you're taking away just one unit. Since there are no units in 31,000, you borrow from the thousands place, making it 30,999.
Think about the number line: to go backward (find what comes before), you subtract. To go forward (find what comes after), you add.
Yes! Every whole number has a predecessor, except for 0 if we're only working with whole numbers. The predecessor of 1 is 0, predecessor of 0 would be -1.
Same rule applies! For numbers like 1,000 or 50,000, just subtract 1. The predecessor of 1,000 is 999, and 50,000 becomes 49,999.
