Question

(1,47:1,4-1,5)*(-5/9):(-0,15)​

Answer 1

(1,47 : 1,4 - 1,5) · (-5/9) : (-0,15) = - 1 целая 2/3

1) 1,47 : 1,4 = 1,05

2) 1,05 - 1,5 = - 0,45

3) - 0,45 · (-5/9) = - 45/100 · (-5/9) = 9/20 · 5/9 = 5/20 = 1/4

4) 1/4 : (-0,15) = 1/4 : (-15/100) = 1/4 : (-3/20) = 1/4 · (-20/3) = - (1·5)/(1·3) = - 5/3 = - 1 целая 2/3
