Ordering decimals can be done in an ascending order or descending order. Ascending order is arranging numbers from smaller to greater. Descending order is arranging numbers from greater to smaller. Decimal number is placing a decimal point between the digits. The decimal numbers need to be compared before ordering them. If the given decimal numbers are equal to each other they are represented by ‘=’. If the given decimal numbers are greater than each other they are represented by ‘>’. If the given decimal numbers are less than each other they are represented by ‘<’.
Example 1: Order the following decimal numbers from smaller to larger fraction: 2.3, 7.5, 6.5, 1.2, and 4.6.
Solution: Given are five decimal numbers 2.3, 7.5, 6.5, 1.2, and 4.6 in random order.
Arranging from smaller to larger is called as ascending order.
The number with the greater whole number part is greater.
This gives 1.2 < 2.3 < 4.6 < 6.5 < 7.5.
Hence, ascending order of the decimal is: 1.2, 2.3, 4.6, 6.5, and 7.5.
Question: Multiple choice question (Pick the correct option.)
Order the decimal number 10.5, 10.6 and 10.7 from greater to smaller?
a) 10.7, 10.6, 10.5 b) 10.5, 10.6, 10.7 c) 10.6, 10.7, 10.5 d) None of these.
Correct answer: option a.
Explanation: Given are three decimal numbers 10.5, 10.6 and 10.7.
Arranging from larger to smaller be called as descending order.
The numbers have same whole number so compare the decimal part.
This gives 10.7 > 10.6 > 10.5.
