Question

2. What should be added to 7/12 to get -4/5​

Answer 1

Answer:

-83/60

Step-by-step explanation:

Let the quantity to be added is m.

Thus,

7/12 + m = -4/5

m = -4/5 - 7/12

Take GCD, make the denominators equal and then add 'em up.

m = (-48 -35)/60

m = -83/60

Answer 2

suppose,

the no. to be added be x

so, the equation formed will be,

$\frac{7}{12} + x=-\frac{4}{5}$

moving the no. to the one side,

$x=-\frac{4}{5} -\frac{7}{12}$

LCM of 5 and 12 is 60 so, putting the value in the equation,

$x=\frac{-48-35}{60}$

upon solving the above equation,

$x=-\frac{83}{60}$

so, the no. that should be added to $\frac{7}{12}$  get $-\frac{4}{5}$ is $-\frac{83}{60}$
