Arrange the following decimal numbers in ascending order:

56.43,  89.23,  65.98,  14.67

The given numbers are: 56.43,  89.23,  65.98,  14.67

First, compare the whole part of the decimal number.

In 56.43, the whole part is 56.

In 89.23, the whole part is 89.

In 65.98, the whole part is 65.

In 14.67, the whole part is 14.

We know that the whole number part with a greater number will be greater.

Therefore, ascending order of these numbers is 14.67 < 56.43 < 65.98 < 89.23
