Question

Ajutațima la exercițiul ăsta plizz
x=4×(17,375-9,125)× 1 supra 11
y=[3,(15)-2,(45)× 11 supra 23

Answer 1

x=4x8,25x1/11
x=33x1/11=33/11=3

3,(15)=3 intregi 15/99=(3x99+15)/99=312/99=104/33
2,(45)=2 intregi 45/99=(2x99+45)/99=243/99=81/33
y=(104-81)/33 x 11/23
y=23/33 x 11/23
y=(23x11)/(23x33)
y=1/3
