Ket [755]

Answer:

Option (2)

Step-by-step explanation:

Option (1).

2(\frac{2}{5}x+2)=2\frac{2}{5}x+1

\frac{4x}{5}+4=\frac{12}{5}x+1

Therefore, both the sides of the expression are not equal.

False.

Option (2).

2(\frac{2}{5}x+2)=\frac{4}{5}x+4

\frac{4x}{5}+4=\frac{4}{5}x+4

True.

Option (3).

2(\frac{2}{5}x+4)=\frac{4}{5}x+2

\frac{4}{5}x+8=\frac{4}{5}x+2

False.

Option (4).

2(\frac{2}{5}x+4)=2\frac{2}{5}x+8

\frac{4x}{5}+8=\frac{12}{5}x+8

Both the sides are not equal.

False.
