POMOCY!!!!!!!!!!!!!!!!!!!!!!

Answer 1

a) -13,1-2,5 =
= - 15,6

b) 17,21-20,03 =
= -2,82

c) -0,82*(-0,3) =
= 0,246

d) 0,92:2,3 =
= 0,4

e) 2,75:1,1 =
= 2,5

f) 1,236:2,01 =
≈ 0,615

g) 1 1/3*0,5 =
= 4/3 * 1/2 =
= 2/3

h) -0,75+1 1/2 =
= -3/4 + 3/2 =
= -3/4 + 6/4 =
= 3/4

i) 5,25:(-1 1/2) =
= 5 1/4 : (-3/2) =
= 21/4 * (-2/3) =
= - 7/2

j) -5 1/5-3,1 =
= - 5,2 - 3,1 =
= - 8,3

k) -2 1/15-(1,3)=
= - 31/15 -13/10 =
= -62/30 - 39/30 =
= -101/30 =
= - 3 11/30

l) 1,2:(-2 1/3) =
= 12/10 : (-7/3) =
= 12/10 * (-3/7) =
= -36/70 =
= -18/35
