Question

C) 5×60-12×60; 6×(2+18-10); d) 12×9+4×150; 392×10-(4×5+16)

Answer 1

c) 5x60-12x60
    300-720=-420

   6 x (2+18-10)
   6 x (20-10)
   6 x 10 = 60

D) 12x9+4x150=
     108+600=708

    392x10-(4x5+16)
    3920-(20+16)
    3920-36= 3884

Answer 2

5x60-12x60=60(5-12) =60x(-7) =-420 ;6x(2+18-10) = 6x10 = 60 ; 12x9+4x150 = 108+600 = 708 ; 392x10-(4x5+16) = 3920-(20+16) = 3920-36 = 3884
