Answer:
A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction. 
 ↔  .5 ↔  .5
- 5  ↔ 5.0
 ↔ 2.0 ↔ 2.0
- -13  ↔  -13.0
- 0.38462... ( ) )
An irrational number is a number that is NOT rational. It's the complete opposite!
- π  ↔  3.14159
- .13133133...
 ↔  0.86603... ↔  0.86603...
- - ↔  -2.23607... ↔  -2.23607...
 ↔   2.23607... ↔   2.23607...

 624/27
624/27
first you have to know what number that can be subtracted by 62 
1. do 27 times 2 equal 54 then you subtract 62 by 54 equal 8 then you put 84 together that will 84 then multiply 27 times 3 = 81 then subtracted by 84 
84-81 equal 3 
In the calculator the answer is 23.1111111111
