Question

today, you will play \you be the teacher\! you will need to spot reasonable answers to math problems. lets warm up by using rounding to estimate.
estimate 6.8 + 1.09.
first, round each number to the nearest whole number.
6.8 rounded to the nearest whole number is ?
1.09 rounded to the nearest whole number is ?

Explanation:

Step1: Round 6.8 to whole number

To round \( 6.8 \) to the nearest whole number, look at the decimal part (\( 0.8 \)). Since \( 0.8 \geq 0.5 \), we round up. So \( 6.8 \) rounded to the nearest whole number is \( 7 \).

Step2: Round 1.09 to whole number

To round \( 1.09 \) to the nearest whole number, look at the decimal part (\( 0.09 \)). Since \( 0.09 < 0.5 \), we round down. So \( 1.09 \) rounded to the nearest whole number is \( 1 \).

Answer:

For \( 6.8 \) rounded to the nearest whole number: \( 7 \)
For \( 1.09 \) rounded to the nearest whole number: \( 1 \)
