Answer:

To write the decimal number as fractions or mixed numbers we follow the following steps:

Step 1: The digits to the right of the decimal point are the numerator of the fraction.

Step 2: The denominator is 10 for tenths, 100 for hundredths, 1000 for thousandths, 10,000 for ten-thousandths and so on.

Step 3: If the decimal has a whole number part, it will be written as a mixed number with the same whole number part.

Step 4: After we write a decimal as a fraction or a mixed number make sure the fraction is in lowest term.

Here the given decimal number is .

The digit to the right of the decimal point , are the numerator of the fraction. The denominator is because the rightmost digit is in the tenths place. Therefore

Answer:

To round decimal numbers we follow these steps:

Step 1: Find the place to which the rounding is being done. Draw a cut off line after that place to sow that we are cutting off and dropping the rest of digits.

Step 2: Look only at the first digit we are cutting off.

Step 3: If this digit is 4 or less the part of the number we are keeping stays the same and if the digit is 5 or more we must round the part of the number we are keeping.

Step 4: we can use the symbol to indicate that the rounded number is now an approximation.

We wish to round here the decimal number to the nearest tenth.

At first we draw a cut-off line after the tenth place. We are cutting off the , it will be dropped.

The first digit cut is 4 or less, so the part we are keeping stays the same. Therefore we can write .

Answer:

Consider that the number 499,501

To round 499,501 to nearest thousand:

Observe the digit, which is in the hundred place. 5 is at hundred place.

If 5 or more at hundred place, add 1000 to 499000 to round the nearest thousands.

Therefore, Thus the nearest thousands of 499,501 is .
