To use techniques from these notes, simultaneously move decimal points to the right, until you get at least one whole number.
Example 1. Calculate `11.5-:4.6`.
Simultaneously move decimal point one position to the right: `115-:46`.
We obtained two whole numbers, so can perform long division as always: `115-:46=2.5`.
Now, let's see an example which leads to dividing decimal by a whole number.
Example 2. Calculate `7.68-:2.4`.
Simultaneously move decimal point one position to the right: `76.8-:24`.
We obtained one whole number and now can divide decimal by a whole number: `76.8-:24=3.2`.
Final example leads to dividing whole number by a decimal.
Example 3. Calculate `16.54-:3.308`.
Simultaneously move decimal point two positions to the right: `1654-:330.8`.
We obtained one whole number, so can divide whole number by a decimal: `1654-:330.8=5`.
Now, it is time to practice:
Exercise 1. Find `3.8-:1.9`.
Exercise 2. Calculate `32.4-:0.16`.
Exercise 3. Find `-0.025-:2.5`.
Exercise 4. Find `-5.95-:(-2.8)`.
Exercise 5. Find `3.4-:0.008`.
