a) 6,75 kg + 6,75 kg + 6,75 kg
= 6,75 kg x 3
= 20,25 kg
b) 9,26 x 9 + 9,26
= 9,26 x (9 + 1)
= 9,26 x 10
= 92,6
a, 6,75 kg + 6,75 kg + 6,75 kg = 6,75kg x 3 =20.25kg
b,9,26 x9 + 9,26 = 9,26 x ( 9 + 1) = 92,6
a,6,75 kg+ 6,75 kg + 6,75 kg
=6 kg+ 0,75 kg+ 6 kg+ 0,75 kg+ 6 kg+ 0,75 kg
=(6x3) kg+ (0,75 x3) kg
=18 kg+ 2,25 kg
=20,25 kg
b,9,26x9+ 9,26
=9,26x9+9,26x1
=9,26x(9+1)
=9,26x10
=92,6
a) 6,75 + 6,75 +6,75
=6,75*3
=20,25
b)9,26*9+9,26
=9,26*9+9,26*1
=9,26*(9+1)
=9,26*10
=92,6
cứ làm theo cách đó nhé
a)=6,75kg*3
=20,25kg
b)=9,26*(9+1)
=9,26*10
=92,6
a,=6,75kgx3
=20,25kg
b,=9,26x(9+1)
=9,26x10
=92,6
