### Class 6 Maths Chapter 8 Exercise 8.3 Solution in Videos

#### Like and Unlike Decimals

##### Like Decimals:

Decimals having the same number of decimal places are called like decimals.

For example, 2.1, 4.6, 8.5 etc. and 2.01, 4.06, 8.05 etc. are groups of like decimals.

##### Unlike Decimals:

Decimals having different number of decimal places are called unlike decimals. For example, 3.6, 5.58, 6.879 etc. are unlike decimals.

Note: The addition of zeroes to the extreme right of a decimal part does not change the value of the decimal number, i.e., 6.3 = 6.30 = 6.300 = 6.3000 etc. Such decimals are called equivalent but unlike decimals. Thus, without changing the value of a decimal number, the number of decimal places can be increased simply by adding required number of zeroes to extreme right of its decimal part.

##### Conversion of Unlike Decimals into Like Decimals

Example 1:

Express 4.3, 0.752, 52.56, 183.06 as a set of like decimals.

Here, the decimal number having highest decimal places is 0.752. It has 3 decimal places. Therefore, we have to convert other decimals into their equivalent decimals which have three decimal places, i.e., 4.3 = 4.300, 52.56 = 52.560 and 183.06 = 183.060 Thus, 4.300, 0.752, 52.560 and 183.060 is a set of like decimals.

##### Comparing Decimals

To compare two decimals, we take these steps:

Step-1: Convert the given decimals into like decimals.

Step-2: First, compare the whole number parts.

Step-3: If they are the same, compare the tenths digits.

Step-4: If they are the same, compare the hundredths digits and so on.

### Class 6 Maths Exercise 8.3 Important Questions

### Compare 18.69 and 11.32.

Given decimals are 18.69 and 11.32.

Let us compare their whole number parts.

Clearly, 18 > 11.

So, 18.69 > 11.32

### Which is greater 24.875 or 24.814?

Given decimals are 24.875 and 24.814.

Here, both the decimals have equal whole number parts, namely 24.

So, we compare their decimal parts.

Their tenths digits are same.

Let us compare their hundredths digits.

Clearly, 7 hundredths > 1 hundredth.

So, 24.875 > 24.814.

### How many numbers are there after the decimal point?

Decimal numbers, such as O. 6495, have four digits after the decimal point. Each digit is a different place value. The first digit after the decimal point is called the tenths place value.

### Does 0 count as a decimal place?

The decimal place accuracy of a number is the number of digits to the right of the decimal point. The decimal point is a period written between the digits of a number. If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy.

### How many decimal places should I round to?

The better rule is to report rounded up to one significant digit, which works across the spectrum of values. Thus a decimal places rule that ignores significant digits does not work.

### What will students learn in exercise 8.3 of 6th standard Maths NCERT?

In exercise 8.3 of 6th standard Maths students will learn how to compare decimals. Example of comparison:

Let us now compare the numbers 32.55 and 32.5.

In this, we first compare the whole part. We see that the whole part for both the numbers is 32 and, hence, equal. We, however, know that the two numbers are not equal. So, we now compare the tenth part. We find that for 32.55 and 32.5, the tenth part is also equal, and then we compare the hundredth part.

We find,

32.55 = 32 + 5/10 + 5/100 and 32.5 = 32 + 5/10 + 0/100, therefore, 32.55>32.5 as the hundredth part of 32.55 is more.

### Is exercise 8.3 of 6th standard Maths important for the exams?

Yes, exercise 8.3 of 6th standard Maths is important for the exams. Questions from this exercise can come in the exams. This exercise has only two questions and one example.
