Round 0.436 to the nearest tenth.

David is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 43 feet and its width is 36 feet. Suppose each can of wood stain covers 172 square feet. How many cans will he need to cover the court?
The area of the court is:
43 feet × 36 feet = 1548 square feet
To find out how many cans of wood stain David will need, we need to divide the total area of the court by the area that can be covered by one can of wood stain:
1548 square feet ÷ 172 square feet per can = 9.01 cans
Rounding up to the nearest whole number, David will need 10 cans of wood stain to cover the court.
To round a number to the nearest tenth, you need to look at the digit in the hundredth place (the second digit after the decimal point).
In this case, the digit in the hundredth place is 4.
Since 4 is less than 5, we round down.
To round 0.436 to the nearest tenth, we round down to 0.4.
