Question

1. a) 5 x [0,(6)+1/9] : 35=
b) (0,1 +1/2+0,01×10) : [(0,17 + 4/5) x 10 + 2,7 x 2]=

2. Sa se determine câtul dintre [18;24] si (18;24)

3. Imagine

Answer 1

1) a) 5 x (6/9+1/9) : 35 =
= 5 x (7/9) : 35 =
= (35/9) x (1/35) =
= (35x1) / (9x35) =
= 1/9

b) (0,1 + 0,5 + 0,1) : [(17/100 + 4/5) x 10 + 5,4)] =
= 0,7 : [(17 + 4*20)/100 * 10 + 5,4] =
= 0,7:(97/100 * 10+5,4 )=
= 0,7 : (97/10 + 54/10) = = 0,7 : [(97+54)/10] =
= 0,7 : (151/10) =
= 7/10 * 10/151 =
= 7/151 =
= 0,04635...
