We round up if the 100 place is 5 or more.
So in this case it is 5 exactly and we round up to 23.5.
Here is the rule:
If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.
It is 2350 when rounded to the nearest ten
2,345 rounded to nearest thousands is 2,000
It is then 56.5 when rounded to the nearest tenth
It is 0.8 when rounded to the nearest tenth
It is: 2300
2345
2340
It is 2350 when rounded to the nearest ten
2,345 rounded to nearest thousands is 2,000
2300
Well, isn't that a happy little number! When we round 5.167 to the nearest tenth, we look at the digit in the hundredths place, which is 6. Since 6 is greater than 5, we round up the tenths place, making it 5.2. And just like that, we have a beautifully rounded number!
65.6
It is then 52.8 when rounded to the nearest tenth
It is then 56.5 when rounded to the nearest tenth
It is 232.4 when rounded to the nearest tenth
It is then 20.2 when rounded to the nearest tenth
It is 0.8 when rounded to the nearest tenth
