Answer 14

The points earned by each choir team during the All-State Competition are as follows:


Choir Choir A Choir B Choir C Choir D
Points 129.5 130.1 130.8 129.8


If points are reported by rounding to the nearest whole number, which team has a different score?
Choir A
Choir B
Choir C
Choir D

Answer 15

Alright so we round up by 1 whole number if the decimal is 0.5 or greater. So what would Choir A be when rounded?

Answer 16

And if the decimal is less than 0.5 than the whole number stays the same but the decimal becomes .0

Answer 17

Based on that could you list what Choi A, B, C and D become when rounded?

Answer 18

Alright lets see 129 130 131 130

Answer 19

Not quite 129.5 also becomes 130 since it has 0.5

Answer 20

So which one is different?

Answer 21

Answer 22

That's fine, that only happens if it is less than 5

Answer 24
