Does 1.645 round to 1.65?
1.645 does round to 1.65.
Since there is a 5 before the 4, it rounds the 4 up to 5. With 5's, you round up, so the 4 goes up a number to 5 in 1.65. Therefore, 1.645 can be rounded to 1.65.
I hope this helps! :)

Sorry for my mistake! :)
depends if you round to the nearest tenth or the nearest hundredth
to the nearest tenth it would be 1.6
for the nearest hundredth, the above is correct as 1.65
To determine if 1.645 rounds to 1.65, we need to look at the digit immediately to the right of the desired rounding decimal place, which is the hundredth place (the second decimal place). In this case, the digit in the hundredth place is 4.
The general rule for rounding is that if the digit in the rounding decimal place is 5 or greater, we round up. If it is less than 5, we round down.
Since the digit in the hundredth place is 4, which is less than 5, we round down. Therefore, 1.645 rounds down to 1.64, not 1.65.
In this case, the answer is no, 1.645 does not round to 1.65.
