Answer:
Step-by-step explanation:
28 rounded to the nearest ten:
'2' is in the 'tens' position....look at the number to the RIGHT
if that number is >= 5 then round the '2' up to 3 o/w leave it as '2'
the number to the right is '8' so round the '2' up to '3'
28 rounded to the nearest ten is then '30'
30 x 9 = 270
