Question

[Lữ Vũ Kim Long]

20,14 x 3 + 20,14 : 0,2 + 20,14 : 0,5

Answer 1

[Trần Phương Thảo]

\(20,14\times3+20,14\div0,2+20,14\div0,5\)

\(=20,14\times3+20,14\div\dfrac{1}{5}+20,14\div\dfrac{1}{2}\)

\(=20,14\times3+20,14\times5+20,14\times2\)

\(=20,14\times\left(3+5+2\right)\)

\(=20,14\times10\)

\(=201,4\)

Answer 2

[Citii?]

20,14 x 3 + 20,14 : 0,2 + 20,14 : 0,5

= 20,14 x 3 + 20,14 : \(\dfrac{1}{5}\) + 20,14 : \(\dfrac{1}{2}\) 

= 20,14 x 3 + 20,14 x 5 + 20,14 x 2

= 20,14 x ( 3 + 5 + 2 )

= 20,14 x 10

= 201,4
