(30 4/5 + 27.4) * 0.9 _______________________= 31.64 - 12 6/25) * 1.12

Question

(30 4/5 + 27.4) * 0.9
_______________________=
31.64 - 12 6/25) * 1.12

Answer 1

((30 4/5 + 27,4) x 0,9):((31,64 - 12 6/25 ) x 1,2) = 2,25
30 4/5 + 27,4 = 30,8+27,4=58,2
58,2*0,9=52,38
31,64 - 12 6/25 = 31,64 - 12,24 = 19,4
19,4*1,2=23,28
52,38:23,28=2,25
