Explicație pas cu pas:

1.)   2/3 : (4/10 + 4/10*1/3) = 2/3 : (12+4) /3= 2/3 *30/16=10/8=5/4

2.)  50 : (1/10 - 1/10*1/5 ) = 50 :4/50 = 50*50/4 =2500/4 =625

3.)   (8 - 8/3*15/10) *2 = (240-120) /30 *2 = 120/30 *2 =8

4.)  3 - (1 - 1/2)^2 : 4/3 = 3 - 1/4*3/4 = 3 - 3/12 = 3 - 1/4 =11/4

5.)  (4/10)^2 * (1/3 +5/10 : 75/100) = 16/100 * (1/3 + 5/10*4/3)=

     =4/25 * (1/3 + 20/30) =4/25 * 30/30 =4/25 *1 =4/25
