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 $7$. $1.09$ rounded to the nearest whole number is $1$. which whole number is the best estimate for $6.8 + 1.09$? $6$ $7$ $8$ $9$

Explanation:

Step1: Round each number

6.8 rounded to nearest whole number: 7 (since 0.8 ≥ 0.5, round up).
1.09 rounded to nearest whole number: 1 (since 0.09 < 0.5, round down).

Step2: Add the rounded numbers

Add the rounded values: \( 7 + 1 = 8 \).

Answer:

8 (corresponding to the option "8")
