43.586 to the nearest tenth :43.6 , hundredth :43.59 , and one: .44

Further explanation
There are general rules used in rounding numbers
-
1. Determine the rounded digit
-
2. Pay attention to the digits afterward (right). If the digit shows the numbers 0, 1, 2, 3 or 4, then the digit to be rounded is fixed, and the digit on the right is 0 all
-
3. If the digit on the right shows the numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added to one, and the digit on the right side is made all 0
In rounding the nearest hundreds number, then we see the digit in the number tens (right of the digit hundreds), if it is worth 0, 1, 2, 3 or 4, then it remains, but if it shows numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added one, and the right-hand side is 0
Calculated from the decimal point, the place on the right represents tents, hundredths, thousandths, etc.
a. 43.586
Decomposition
ten : 4
one : 3
tenth : 5
hundredth : 8
thousandths : 6
For the tenth number is 5, the value on the right is 8 then rounded become 43.6
For the hundredth number is 8, the value on the right is 6 then rounded become 43.59
for the one number is 3 , the value on the right is 5 then rounded become 44
b.243.875
Decomposition
hundred : 2
ten : 4
one : 3
tenth : 8
hundredth : 7
thousandths : 5
a. For the tenth number is 8, the value on the right is 7 then rounded become 243.9
For the hundredth number is 7, the value on the right is 5 then rounded become 243.88
For the ten number is 4, the value on the right is 3 then rounded become 240
For the hundred number is 2, the value on the right is 4 then rounded become 200
