Question

what number should be subracted from -5/13 to get -1 2/5​

Answer 1

Step-by-step explanation:

let the number be X.

x-(-5/13)=-12/5

13x-(-5)=-12/5

65x+25=156

65x=156-25

65x=131

x=131/65

Answer 2

Answer:

LCM of 13 and 5 is 60

-5/13 = (-5×5)/13×5 = -25/60

-12/5 = (-12×13)/5×13 = -156/60

-25/60 - (-156/60) = -25/60 + 156/60 = 131/60
