How to square root a fraction-__**√25/36**__You take **25** and square root it which it would equal **5**.Then you take **36** and square root it which would equal **6**. your answer is **5/6**. How to square root decimals-__**√1.21**__Pretend there is no decimal at first. **√121**.The square root of **121** is **11**.You have to put the decimal back so its now **1.1** **√1=1** **√****4=2**  **√****9=3**  **√****16=4**  **√****25=5**  **√****36=6**  **√****49=7**  **√****64=8**  **√****81=9**  **√****100=10**  **√****121=11**  **√****144=12**  **√****169=13**  **√****196=14**  -Pg. 155 Image- Whole numbers- Numbers without fractions, decimals, or negatives. Integers- Numbers that can be negative or positive, no fractions or decimals. Rational Numbers- Includes integers, whole numbers, and terminating fractions (have an and do not need a bar notations). Irrational Numbers- Decimals. Never ending number. Such as Pi. 3.14 and so on.
