a)29,45 x 0,2 x 5
= 29,45 x (0,2 x 5)
= 29,45 x 1
= 29,45
b) 40 x 201,5 x 1,25 x 02
= (40 x 1,25) x (201,5 x 0,2)
= 50 x 40,3
= 2015
A) 29.45* ( 0.2*5) =29.45*1=29.45
B) (40*201.5)*(1.25*0.2) =8060*0.25=2015
a, 29.5x (0.2x5)
29.5x1=29.5
b,(40x1.25)x(201.5x0.2)
=50x 40.3=2015

a) 29,45 x 0,2 x 5
= 29,45 x 1
=29,45
b) 40 x 201,5 x 1,25 x 0,2
= ( 1,25 x 0,2 ) x 40 x 201,5
= 0,25 x 40 x 201,5
= 10 x 201,5
=2015
a)29,45x0,2x5= 29,45 x ( 0,2 x5)=29,45x1= 29,45
b)40x201,5x1,25x0,2= 201,5x(1,25x0,2x40)=201,5x10=2015
A)29,45×0,2×5=29,45×(0,2×5)
=29,45×1,0
==>29,45
B)40×201,5×1,25×0,2=(40×1,25)×(201,5×0,2)
=50×40,3=2,015
