Decimal numbers are numbers having whole number and fractional part where both parts are separated by decimal point. When there is equal number of places after the decimal point then that decimal fraction is said to be like fraction. Whereas, when there is unequal number of places after decimal point that decimal fraction is said to be unlike fraction.
For example:
74.110, 110.1453
These two numbers are unlike decimal fractions as the first number has 3 places after the decimal point and the second number has 4 places after the decimal point
So, it can be concluded that when there are unequal number of places after the decimal point the number is said to be unlike decimal fraction.
Here is few examples state whether they are like or unlike decimal fraction. Give reasons why?
(i) 456.23, 452.11, 12.021, 50.21, 332.01, 22.01, 74.21
Are unlike fraction as 456.23, 452.11, 12.021, 50.21, 332.01, 22.01 and 74.21 has 2, 2, 3, 2, 2, 2, 2 places respectively after decimal point. If all the numbers had 2 places after the decimal point then the number would have been like decimal fraction.
(ii) 745.012, 45.011, 36.32, 856.025, 3.021, 65.01, 548.21
