Step-by-step solution for: Fourth Grade Rounding Worksheets
Let's solve the rounding problem step by step. The task is to round each number to the nearest ten-thousand.
- We are looking at the ten-thousands place, which is the 5th digit from the right (e.g., in 12,572, the "1" is in the ten-thousands place).
- To round:
- Look at the digit in the thousands place (the 4th digit from the right).
- If it's 5 or greater, round up.
- If it's less than 5, round down.
