For this case we have the following definitions:
tens place: number of two digits greater than zero
hundreds place: three-digit number greater than zero
thousands place: number of four digits greater than zero
ten thousands place: five-digit number greater than zero
We can apply the definitions to round the following number:
47125
To do this, you must remember that if the previous number is greater than or equal to 5, the next number acquires a unit.
We have then:
tens = 47130
hundreds = 47100
thousands = 47000
ten thousands = 50000
