when this 3-digit number is rounded to the nearest ten, the sum of its digits is 16 .the hundreds digit of this number is 8 and the ones digit is 5 . what is the number?

• 3rd grade -

if the one is 5 and the hundreds is 8, then it is 5._8, and 5 + 8 + _ = 16, so you subtract 5+8 from 16 and get 3, so the number is 5.38

8 __ 5

Rounded to the nearest ten, it's 8 __ 0

8 + 0 + x = 16

x must be 8.

880 = 8 + 8 + 0 = 16

Did you forget to round the number to the nearest 10?
