Answer:
585.1
Step-by-step explanation:
To round this number; 585.055 to the nearest tenth, you need to first know the place value of each of the number and then the rules of rounding off.
Place value is just the value represented by the digit in a number because of its position in that number.
In the digit; 585.055
Moving from left to right, the first 5 stands for five hundred
8 stands for eight tens
The second 5 stands for five ones or five units
0 stands for zero tenth
the first 5 stands for five hundredths
the second 5 stands for five thousands.
Now we move ahead to state the rules of rounding off.
In our case, we are to round to the nearest tenth, since 0 is in the tenth position, 0 is our target number, Now the immediate number after the target number is called the decider. All numbers before the target number are written back the way the are ( that is we are going to re-write 585 without altering anything)
The decider will tell if we are going to re-write our target number the way it is or if we are going to increase it by one. If the decider is from 5 and above, we will increase our target number by 1, but if the decider is from 4 downward, we are going to re-write our target number down without altering anything. ( In this case, 5 is our decider, so we will increase zero by 1)
When you are rounding a decimal number, both the decider and every other number after the decider will not be written back again.
So from the above explanation , 585.055 can be rounded up to 585.1 to the nearest tenth
