Step-by-step explanation:

Rounding Off:

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

Decimal:

One of the number types in algebra that has a whole integer and a fractional portion separated by a decimal point is a decimal. The decimal point is the dot that appears between the parts of a whole number and a fraction. An example of a decimal number is $34.5$.

The four distinct types of decimals are terminating, non-terminating, recurring, and non-recurring. Decimal encompasses all four types of decimals.

(1) $8.1347$, correct to three decimal places.

Rounding to Three Decimal Places:

First, count three places to the right of the decimal point. The fourth decimal place, or ten thousandths place, is the number that comes after three decimal places. Simply round up and add 1 to the thousandths place if the digit in the ten thousandths place is greater than or equal to 5.

The number $8.1347$ correct to three decimal places is $8.135$.

(2) $0.047$, correct to two decimal places

Rounding to Two Decimal Places:

The second place to the right of the decimal point, or the hundredths place, is used to round a decimal value to two decimal places.

The number $0.047$ correct to two decimal places is $0.05$.
