36 + (-7) x 6 - (-16)
= 36 + (-42) + 16
= 36 - 42 + 16
= - 6 + 16
= 10

————————————————
160 : 4 x (-3) + 269
= 40 x (-3) + 269
= -120 + 269
= 149

————————————————
0,8 : 50% x 10/4
= 8/10 : 50/100 x 5/2
= 4/5 : 1/2 x 5/2
= 4/5 x 2 x 5/2
= 4

1.
36 + (-7) x 6 - (-16)
= 36 + -42 + 16
= - 6 + 16
= 16 - 6
= 10

2.
160 : 4 x (-3) + 269
= 40 x (-3) + 269
= -120 + 269
= 269 - 120
= 149

3.
0,8 = 8/10 = 4/5
50% = 50/100 = 1/2
2 2/4 = 10/4 = 5/2
maka
0,8 : 50% x 2 2/4
= 4/5 : 1/2 x 5/2
= 4/5 x 2 x 5/2
= (4 x 2 x 5) / (5 x 2)
= 40 / 10
= 4
