Question

X=[5,(6)-15/4+0,75]×3/2

Answer 1

x=(5si2/3-15/4+3/4)*3/2
introducem intregii in fractie (5*3+2)/3=17/3
x=(17/3-12/4)*3/2, aducem la numitorul comun in paranteze 
17*4/12-12*3/12=(68-36)/12=32/12=8/3
x=8/3*3/2
x=8/2
x=4

Answer 2

5,(6)=56/9
0,75=75/100=15/20=3/4
x=(56/9-15/4+3/4)x3/2
x=(56/9-12/4)x3/2
x=(56/9-3)x3/2
x=[56/9-27/9)x3/2
x=29/9x3/2
x=29/6
x=4,8(3)
