Question

What should be added to -3/5 to get -1/2.?

Answer 1

Step-by-step explanation:

its decimal expansion is 0.714285714....

so, it is terminating repeating decimal expansion.

Answer 2

Answer:

hmm

it is

-3/5 + x = -1/2

x = -1/2 + 3/5

x = (-5 + 6)/10

x = 1/10

[ use this in a written test ]

or, it can be solved as

-3/5 + x = -1/2

here, x will be 0.5/5 [ assumed ]

-3/5 + 0.5/5 = -1/2

(-3 + 0.5)/5 = -1/2

-2.5/5 = -1/2

-1/2 = -1/2

[ this method is only if you want to solve quickly, in a written test, it will be considered wrong ]
