Round the number to the hundredths place.
12,863.14846
a.
12,863.14
b.
12,863.15
c.
12,900
d.
12,800

if we round to the hundredth place, this means that we round to one hundredth, that is 0.01- after this position there will only be 0s.

So for us

12,863.14846
changes into

12,863.14

or does it? the first number we cut off is bigger than 4, so we actually have to increase the previous number: the correct answer  is:



12,863.15

10.5 : 12 : 13.5

Step-by-step explanation:

12 ÷ 8 = 1.5 (multiply this by all of the known numbers

8 x 1.5 = 12

7 x 1.5 = 10.5

9 x 1.5 = 13.5
