1.Rozwiąż działania:
(5/6 + 1/3) : (2 2/3 - 1,75) =


17/40 - 0,2
__________ =
1 3/5

2.Do liczby 182,34 dodaj różnicę liczb 11,1 i 0,99




Odpowiedź :

(5/6 +1/3) : 2 2/3 - 1,75) = (5/6 +2/6) : (8/3 - 175/100) = 7/6 : (800/300 - 525/300) = 7/6 : 275/300 = 7/6 x 300/275 = 350 275 = 14/11 = 1 3/11


(17/40 - 0,2) : 1 3/5 = (17/40 - 2/10) : 8/5 =( 170/400 - 80/400 ) : 8/5 = 9/40 :8/5 = 9/40 x 5/8 = 9/8 = 1 1/8


182,34 + (11,1 - 0,99) = 182,34 + 10,11 = 192,45
1.(5/6+1/3)÷(2 2/3-1,75)=(5/6+2/6)÷(8/3-7/4)=7/6÷(32/12-21/12)=7/6*12/11=14/11=1,28


17/40-0,2
_______ =17/40-2/10
__________ =17/40-8/40
1 3/5 8/5 _________ =9/40÷8/5=9/40*5/8=9/64=0,14
8/5

2.182,34+(11,1-0,99)=182,34+10,11=192,45
