Question

calculează 11 supra 15 plus 7 supra 15 minus 8 supra 15​

Answer 1

11 supra 15 +7 supra 15 - 8 supra 15 = 10 supra 15

11 supra 15+ 7 supra 15 =18 supra 15

18 supra 15 - 8 supra 15 =10 supra 15

Answer 2

11/15  +  7/15  -   8/15

$\it \dfrac{11}{15}+\dfrac{7}{15}-\dfrac{8}{15}=\dfrac{11+7-8}{15}=\dfrac{\ 10^{(5}}{15}=\dfrac{2}{3}$
