prosze o szybką odpowiedz :-)

Answer 1

[1 i 5/7 :(3,6 - 1,8 * 1 i 1/3)] * 1,4=

= [ 1 i 5/7 :(3 i 6/10 - 1 i 8/10 * 4/3)] * 1 i 4/10=

= [1 i 5/7 : (3 i 6/10 - 18/10 * 4/3)] * 14/10=

= [1 i 5/7 : (3 i 6/10 - 6/5 * 2/1)] * 14/10=

= [1 i 5/7 : (3 i 6/10 - 12/5)] * 14/10=

= [1 i 5/7 : (3 i 6/10 - 2 i 2/5)] * 14/10=

= [ 1 i 5/7 : (3 i 3/5 - 2 i 2/5)] * 14/10 =

= [1 i 5/7 : 1 i 1/5 ] * 14/10=

= [ 12/7 : 6/5] * 14/10=

= [ 12/7 * 5/6] * 14/10=

= [ 2/7 * 5/1] * 14/10=

= 10/7 * 14/10 = (skracam ułamki)

= 1/1 * 2/1=

= 2/1=

= 2
