pakai caranya ya,lengkap caranya

Answer 1

1. 6 x (294-256) : (9,75-5,95)
= 6 x 38 : 3.8
= 6 x 10
= 60

Answer 2

1) 6x(294-256):(9,75-5,95)
=6x(38):(3,8)
=228:3,8
=60

2) 692+(57,6:1,2)-(239-228)
=692+48-11
=729

3) (144:7)x(105:8)+(-17)
=20,57x13,1-17
=269,47-17
=252,47

4) -9x(-18)-(27,5:5)
=162-5,5
=156,5
