The first digit of two different numbers is in the hundreds millions place. Both numbers contain the same digits. Can you determine the greater of the two numbers and Explain.

Just start with the leftmost digit of each number, and compare corresponding digits. The first time one is greater than the other, that number is the greater.
You know that, say, 6 > 2
So, if your two numbers are something like
7836219
7832...
you can immediately see that the first is greater, no matter what follows from there on to the right.
