Question

Using digits 1-7 , create a 7 digit number that can be rounded to 6,300,000.

Answer 1

Let’s create a 7 digit number composed of 1-7 digits to be rounded to 6,300,000.

Let's have 6,274,153 in where:
3=ones, 5=tens, 1=hundreds, 4= thousands, 7= ten thousands, 2= hundred thousands, 6 = millions.

Another rule in rounding off numbers. Any number less than 5, round down. Any number more than 5, round up.
Therefore: 6,274,153 will be rounded to 6,300,000.
