Question

12 3\5-1 1\3*0,3=
20-12 2\3:5\6=
4 1\5*2,7:5,67=
27 3\4:4 5\8*1 1\5=

Answer 1

a) 12 3\5-1 1\3*0,3= 12 i 3/5 - 4/3 * 3/10 = 12 i 6/10 - 4/10 = 12 i 2/10 = 12 i 1/5 wynik

b) 20-12 2\3:5\6= 20 - 38/3 * 6/5 = 100/5 - 76/5 = 24/5 = 5 i 4/5 wynik

 

c) 4 1\5*2,7:5,67= 21/5 * 27/10 : 5 i 67/100 = 21/5 * 27/10 * 100/567 = 576/50 * 100/567 = 2wynik

d) 27 3\4 : 4 5\8 * 1 1\5=  111/4 : 37/8 * 6/5 = 111/4 * 8/37 * 6/5 = 24/4 * 6/5 = 36/5 = 7 i 1/5 wynik

 

TEŻ TO MIAŁAM, POZDRAWIAM :)

Answer 2

12 3\5-1 1\3*0,3= 12 i 3/5 - 4/3 * 3/10 = 12 i 6/10 - 4/10 = 12 i 2/10 = 12 i 1/5

20-12 2\3:5\6= 20 - 38/3 * 6/5 = 100/5 - 76/5 = 24/5 = 5 i 4/5

4 1\5*2,7:5,67= 21/5 * 27/10 : 5 i 67/100 = 21/5 * 27/10 * 100/567 = 576/50 * 100/567 = 2

27 3\4 : 4 5\8 * 1 1\5=  111/4 : 37/8 * 6/5 = 111/4 * 8/37 * 6/5 = 24/4 * 6/5 = 36/5 = 7 i 1/5
