What is -1.1 repeating as a fraction

Thepotemich [5.8K]

$Hey \\ There!$

$\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11 \\ \\ 1(10)= 10 \\ \\ \\ Fraction: \frac{-11}{10}$ this is also $equal$ to: $-1\frac{1}{10}$

Your answer would probably be: $\frac{-11}{10} = -1\frac{1}{10}$

Good luck on your assignment and enjoy your day!
