Question

Tính: 

(1.4 + 2.6) × 2

70 ÷ (4.6 + 3.4 - 1)

Answer 1

(1,4 + 2,6) x 2 = 4 x 2 = 8

70 : (4,6 + 3,4 - 1) = 70 : 7 = 10

Answer 2

\(\left(1,4+2,6\right)\times2\)

\(=4\times2=8\)

\(70\div\left(4,6+3,4-1\right)\)

\(=70\div7=10\)

Answer 3

(1,4 + 2,6) x 2 = 4 x 2 = 8

70 : ( 4,6 + 3,4 - 1) = 70 : 7 = 10

Answer 4

1.4 + 2.6) × 2 = 4 × 2 = 8

 

70 ÷ (4.6 + 3.4 - 1) = 70 ÷ 7 = 10
