Answer 1

Step 1: First make the number of digits after the decimal point equal by putting zeroes to the extreme right side of the decimal part, if required. The like decimals are$23.40,32.40,23.34,32.24,32.42,23.24$.

Step 2: Compare the whole number parts. The decimal with greater whole number is greater. Here, the whole numbers are $22,23,23,32,32,32$ In ascending order.

Step 3: If the whole number parts are equal, compare the tenths digits. The decimal with the bigger digit in the tenths place is greater.

Step 4: If the tenths digits are equal, compare the hundredths digits, and so on. We get the results. Hence, the given decimals in ascending order are .

$\therefore 22.34<23.24<23.4<32.24<32.4<32.42.$
