Answer 1

1)  ( 1 1/3 + 1 2/3  * 1,2) : 1 2/3 - ( 1,75: 1 1/8 - 2 1/3 : 5,25) * 0,9  wszystko dzielone przez ( 5 5/6 - 5,5 ) * 0,3

= [(4/3 + 5/3 * 12/10) : 5/3 - ( 175/100 : 9/8 -  7/3 : 525/100) * 9/10 ] / (35/6 - 55/10) *3/10 = [4/3 +2) *3/5 - (175/100 * 8/9 - 7/3 * 100/525) * 9/10)] / (175/30 - 165/30) *3/10 = [(10/3)*3/5 - (175/25*2/9 - 1/3* 100/75) * 9/10] / (10/30 * 3/10) =[2 - (14/9 - 4/9)*9/10] / (1/10) = (2 - 10/9 * 9/10) * 10/1 = (2 - 1) * 10 = 10
