Sottrai a 11/10 la somma di 3/5 e 1/3

===============================================

$\frac{11}{10}-\big(\frac{3}{5}+\frac{1}{3}\big)$=

=$ \frac{11}{10}-\big(\frac{9+5}{15}\big)$=

=$ \frac{11}{10}-\frac{14}{11}$=

=$\frac{33-28}{30}$=

=$\frac{5}{30}$ =

=$\frac{1}{6}$.

Sottrai a 11/10 la somma di 3/5 e 1/3

=====

11/10-(3/5+1/3) =

11/10-(9+5)/15 =

11/10-14/15 =

(33-28)/30 =

5/30 = 1/6

Alla frazione  11/10  togliamo la somma (3/5 + 1/3);

espressione:

11/10  - (3/5 + 1/3) =

dentro parentesi tonda: mcm(5; 3) = 15;

= 11/10  - (9/15 + 5/15) =

= 11/10 - 14/15 =

mcm (10;15) = 30

= 33/30 - 28/30 = 

= 5/30; semplificando per 5:

5/30 = 1/6.

Ciao @nadya

$\dfrac{11}{10}-\left( \dfrac{3}{5} +\dfrac{1}{3}\right) =\dfrac{5}{30} =\dfrac{1}{6}$
