What is 110.4 x 10.2 rounded to the nearest whole number
nexus9112 [7]

Answer:

1,126 or 1100

Step-by-step explanation:

This is the answer because:

1) 110.4 x 10.2 is equal to 1,126.08

2) 1,126.08 rounded to the nearest whole number is 1,126 because the number before 6 is is 0 which makes the number stay the same

3) The answer can also be 1100 because you first have to round 110.4 and 10.2 to the nearest whole numbers which will get you 110 and 10 since the rounding numbers are below 5

3) Then, multiply 110 and 10 which is 1100

Hope this helps!
