Ok to create a number less than 3 hundred thousand, 7 ten-thousands, 5 thousands, 2 hundreds and 1 ten, we need to know the place values of large numbers. If it is less than 3 hundred thousand: There would be 6 decimal places or: > 300,000
7 ten thousands: 70,000
5 thousand: 5,000
1 ten: 10
Join together all these numbers to get something like: 275,010
