20,25 nhé

6,75kg + 6,75kg + 6,75kg = 6,75kg x 3 = 20,25kg.

… = 6,75kg x 3 = 20,25kg

a) \(6,75kg+6,75kg+6,75kg=3\cdot6,75=20,25\left(kg\right)\)

b) \(7,14m^2+7,14m^2+7,14m^2\cdot3=7,14\cdot5=35,7\left(m^2\right)\)

c) \(9,26dm^3\cdot9+9,26dm^3=9,26\cdot10=92,6\left(dm^3\right)\)

a) 6,75 kg + 6,75 kg + 6,75 kg = 6,75 kg x 3 = 20,25 kg.

b) 7,14 m + 7,14 m + 7,14 m x 3 = 7,14 m x 2 + 7,14 m x 3 = 14,28 m + 21,42 m = 35,7 m.

c) 9,26 dm x 9 + 9,26 dm = 9,26 dm x ( 9 + 1 ) = 9,26 dm x 10 = 92,6 dm.

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) 6,75kg + 6,75kg + 6,75kg = 6,75kg x 3 = 20,25kg

b) 7,14 m² + 7,14 m² + 7,14 m²  = 7,14 m² x 3 = 21,42 m²

c) 9,26 dm3 x 9 + 9,26 dm3 = 9,26 dm3 x ( 9 + 1 ) = 9,26 dm3 x 10 = 92,6 dm3

6,75 kg + 6,75 kg + 6,75 kg = 6,75 kg x 3 = 20,25 kg

7,14m2 + 7,14m2 + 7,14m2 x 3 = 7,14m2 x 1 + 7,14m2 x 1 + 7,14m2 x 3 = 7,14m2 x ( 1 + 1 + 3 ) = 7,14 m2 x 5 = 35,7 m2

9,26 dm3 x 9  + 9,26 dm3 = 9,26 dm3 x 9  + 9,26 dm3 x 1 = 9,26dm3 x ( 9 + 1 ) = 9,26dm3 x 10 = 92,6 dm3

6,75 *3= 20,25

7,14 *3*3=64,26

9,26*2*9=166,68

a) =6,75kg.(1+1+1)=6,75.3=20,25kg

b) =7,14.(1+1+3)=7,14.5=35,7m2

c) =9,26.(9+1)=9,26.10=92,6dm3
