What is 63.63 repeating as a fraction

x = 700/11

Step-by-step explanation:

let x = 63.63...(by repeating i assume you mean the 63 is repeated as 63.636363...)

therefore 100x = 6363.63..

100x-x =6300 (the recurring bit has been cancelled out which is what you should always aim to do)  

99x=6300

x = 6300/99  

cancel down

x = 700/11

hope that helps! :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
