If a mod (Not going to specify because deletes questions relating to complaints) deleted most of your brainliest answers for no reason in one day, and I'm not getting any response from the developers, what can I do alternatively?

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
