Answer 1

Răspuns:

a) -275/100 - 15/10 = (-275-150)/100 = -425/100= -4,25

b) -4/9 × -3/2 = 2/3

c) (583-58)/900 × -9/7 = 525/900 × -9/7 = - 525/100= -5,25

d) 1 : -22/7 = 1× -7/22= -7/22 = -0,3(18)

e) -65/16 × 8/65 = -1/2

f) [(35-9)/60 - (50-24)/240] × -110/13 =

(26/60 - 26/240) × -110/13 =

(104-26)/240 × -110/13 =

78/240 × -110/13 =

-66/24 =

-11/4 =

-2,75
