the 2nd expression is the answer
Answer:
-9
Step-by-step explanation:
The number 9.210 is greater. The least place value is the 0 (Zero) and the 1 (One). This is because the 9 (Nine) and the 2 (Two) in 9.207 and 9.210 is the same numbers. There so, you can't compare those 2 (Two) numbers.
For the first digit, you have two possible choices: 1 or 2. For *each* of those choices, you can choose 1 or 2 for the second digit in the number, and for each of *those*, you can choose 1 or 2 for the third digit of the number.
That’s 2 * 2 * 2 or 8 possible 3-digit numbers you can make with the digits 1 and 2.
