Question

Oblicz [rozpisz] :

c.) 2/3+1/2-0,5 / 0,2-0,8x1/8

Answer 1

2/3 + 1/2 - 1/2 : 2/10 - 8/10 * 1/8

 

2/3 : 2/10 - 8/80 = 2/3 : 16/80 - 8/80 = 2/3 : 8/80 = 2/3 * 80/8 = 6 i 2/3

Answer 2

2/3+1/2-0,5 / 0,2-0,8x1/8= 4/6+3/6-1/2*10/2-8/10*1/8=7/6-10/4-1/10=70/60-150/60-6/60=-86/60=-1 26/60

no chyba że to ma być takie równanie

2/3+1/2-0,5     4/6+2/6-3/6      3/6

--------------- = ---------------- = ------- = 3/6*100/2=300/12=25

0,2-0,8x1/8       0,2*0,1            0,02
