Like and Unlike Decimals Examples

Have you ever thought about what a decimal number is? The term decimal number denotes the numerical quantity present in fractions and not as a whole. The representation of the decimal number is such that the whole part is separated from the fractional part by a decimal point or a dot. For example, 2.35, 1.2, 5.67, and 7.08 represent decimal numbers, which lie between two whole numbers or integers. In the given article, children would gain insight into the like and unlike decimals and how to convert, unlike decimals into like decimals. This is the most common topic used in mathematical calculation. Let us understand more about it.


What are Like and Unlike Decimals?

Like decimal numbers are those decimal numbers that have the same number of digits after the decimal point. For example, 2.46, 6.09, and 3.87 are called decimal numbers.

Further, unlike decimal numbers, those decimal numbers have a different number of digits after the decimal point. For example, 2.657, 3.04, and 1.871 are called, unlike decimals.

Convert Unlike Decimals into Like Decimals

The best and most feasible way to convert unlike decimals into like decimals is by adding zeros to the right of the decimal place, which does not lead to a change in the actual value. Steps to be followed when changing unlike decimals into like decimals are given underneath:

  1. Write the given expression

  2. Write the like and unlike decimal numbers from the given expression separately by enclosing them within brackets

  3. Then, convert unlike decimals into like decimals by putting 0s to the right of the decimal point

Thus, the expression gets converted to decimal numbers.


Like and Unlike Decimals Solved Examples

Q 1. Convert the following decimals to like decimals: 1.7, 2.35, 6.135.

Ans: Follow the below-given steps to convert the unlike decimals into the like decimals, i.e.

  1. Write the given decimals

1.7, 2.35, 6.135

  1. Separate the like and unlike decimals. If there is no separation, then right as it is, i.e. 1.7, 2.35, 6.135

  2. Further, we need to convert each of the decimal numbers to the like decimal number, which has an equal number of digits after the decimal point

1.700, 2.350, 6.135

Thus, the decimal expression is converted to like decimals with the utmost digits at the right of the decimal point.

Q 2. Which of the given decimals is greater, 78.40 or 78.210?

Ans: To compare two decimals, one needs to follow some steps:

  1. Write the given decimal expression

78.40 or 78.210

  1. Now, convert the unlike decimals into like by putting zeros

78.400 or 78.210

  1. As the left side of the decimal point is the same for both the decimal numbers; thus comparison will be based on the right side of the decimal point i.e.

400 is greater than 210

  1. Finally, deciding which decimal is greater than the other

Hence, 78.400 is greater than 78.210.


Practice Problems

Q 1. Convert the decimal points to like decimal points: 11.4, 1.56, 1.8, 1.983.

Ans: 11.400, 1.560, 1.800, 1.983


Q 2. Compare the decimal points:

1.763 or 1.61

Ans: 1.763


Q 3. Transform the following, unlike decimals into like decimals: 1.72, 26.361, 3.35 and 0.9.

Ans: 1.7200, 26.3610, 3.3500 and 0.9000.


Q 4. Separate the following like and unlike decimals.

9.5, 18.235, 4.51, 7.06 and 20.024.

Ans: Like Decimals:

  • With two digits after the decimal point are 4.51 and 7.06

  • With three-digit after the decimal point are 18.235 and 20.024

Unlike Decimals are:

  • 9.5, 4.31 and 18.235

  • 9.5, 7.06 and 20.024

  • 9.5, 7.06 and 18.235

  • 9.5, 4.31 and 20.024
