Step-by-step solution for: Grade 6 Rounding Worksheets: Rounding numbers (up to billions ...
To solve this problem, we need to round each number to the digit that is underlined. Since the underlines are not visible in the image, I will assume that the last digit of each number is the one to be rounded (as is common in such worksheets). Here’s how we’ll proceed:
1. Identify the digit to round to (the last digit).
2. Look at the digit immediately to the right of the one we’re rounding to.
3. If that digit is 5 or greater, round up. If it’s less than 5, round down.
4. Replace all digits to the right of the rounding digit with zeros.
Let’s go through each number step by step:
