Write the greatest number that can be formed from .
There are 6 digits provided, so we can write a 6-digit number. We can use a place-value chart to form the greatest number. Start with the greatest digit:
Use the greatest digit (9) for the greatest place value (hundred thousands). Use the next greatest digit (8) for the next greatest place value (ten thousands). Continue in this way until you use the least digit (1) for the least place value (units).
So, the greatest number that can be formed from is 987 521. Notice that the digits in the number are in order from greatest to smallest.
