Question

(5supra 6+3supra 4)•24 supr 19-(2 supra 3 -1 supra 6 )•4 supra 3

Answer 1

In prima paranteza aducem la numitorul comun, adica 12:19/12 
19/12*24/19 =>se simplifica si se obtine 2
In a doua, aducem la numitorul comun, adica 6 =>1/2
1/2*4/3 =4/6 simplificam si obtinem 2/3
=>(2-1/2)  *4/3 <=>3/2  *4/3 =2

Answer 2

(5/6 + 3/4) * 24/19 - (2/3 - 1/6) * 4/3 = 
(10/12 + 9/12) * 24/19 - (4/6 - 1/6) * 4/3 =
19/12 * 24/19 - 3/6 * 4/3 = 
2 - 2/3 = 
6/3 - 2/3 = 
4/3 = 
1 si 1/3
