Question

$11 supra 5-1 supra10- 3supra 10=$

Answer 1

$\frac{11}{5}$  -  $\frac{1}{10}$  -  $\frac{3}{10}$  =  $\frac{22}{10}$-  $\frac{1}{10}$  -  $\frac{3}{10}$  =$\frac{18}{10}$=$\frac{9}{5}$

Answer 2

$^{2)}\frac{11}{5}- \frac{1}{10}- \frac{3}{10} = \frac{22}{10}- \frac{1}{10}- \frac{3}{10}= \frac{18}{10}=\boxed{1,8}$
