Answer: 32.14   after round off it will be 32

Step-by-step explanation:

This is how to round 32.14 to the nearest whole number. In other words, this is how to round 32.14 to the nearest integer.

32.14 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 32

Fractional Part: 14

 

Our goal is to round it so we only have an integer part using the following rules:

If the first digit in the fractional part of 32.14 is less than 5 then we simply remove the fractional part to get the answer.

If the first digit in the fractional part of 32.14 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.

The first digit in the fractional part is 1 and 1 is less than 5. Therefore, we simply remove the fractional part to get 32.14 rounded to the nearest whole number as:

32

a home building contractor bought 4 2/8 acres for $165,000. What was the cost of each acre? (round to nearest dollar.)
pychu [463]

Answer: $38,824

Step-by-step explanation:

Convert the mixed number 4\ \frac{2}{8} as a decimal number.

Divide the numerator by the denominator and add it to the whole number 4. Then:

4+0.25=4.25acres

Then, knowing that 4.25 acres cost $165,000 , divide this amount by 4.25 acres to find the cost of each acre.

Therefore, you get that the cost of each acre rounded to nearest dollar is:

cost=\frac{\$165,000}{4.25}\\cost=\$38,824
