Zero
You can round it to the nearest 10: Its closer to 90 than it is to 100, so 90 is the answer. Or you can round it to the nearest 100, its closer to 100 than 0, so 100 is the answer
90 100 010 - ___ 090 10 - 1 = 9 0 - 0 = 0 100 - 10 = 90
80 + 10 = 90 - 0 or 80 + 10 = 90 is true
Ask, is 3.9 closer to 0 (the lower multiple of ten) or closer to 10 (the higher multiple of ten)? As it's closer to 0, your answer is 0.
10
There are 90 hundredths in 0.9 90
One
90 is divisible by 10 since 90/10 = 9. It should be obvious that 90 is not divisible by 234,569 which is much larger than 90.
90
90 = (9 x 10) + (0 x 1)
2/5 is closer to 0.
