Question

Thực hiện phép tính:

(4,2 - 5,6) . 3,8 - (25,12 + 13,28) :0,5 - 17,88

Answer 1

\(=\left(-1.4\right)\cdot3.8-38.4\cdot2-17.88=-100\)

Answer 2

\(\left(4,2-5,6\right).3,8-\left(25,18+13,28\right):0,5-17,88\\ =\left(-1,4\right).3,8-38,46.2-17,88\\ =-5,32-76,92-17,88\\ =-100,12\)

Answer 3

=(−1.4) ⋅ 3.8 − 38.4 ⋅ 2− 17.88 = −100

Answer 4

= (−1.4)⋅ 3.8 − 38. 4. 2 − 17. 88 = −100

Answer 5

=(−1.4)⋅3.8−38.4⋅2−17.88=−100

Answer 6

=(−1.4)⋅3.8−38.4⋅2−17.88=−100
