Answer 2

Answer:

(-1/20) should be added to (-7/20) to get (-2/5).

Step-by-step explanation:

Let the number to be added be x,

Then, according to the Question,

(-7/20) + x = (-2/5)

x = (-2/5) - (-7/20)

Taking LCM = 20

x = (-2/5) × (4/4) - (-7/20)

x = (-8/20) - (-7/20)

x = (-8/20) + (7/20)

x = (-1/20)

Hence,

(-1/20) should be added to (-7/20) to get (-2/5).
