Question

What must be subtracted from -9upon 14 to get 11 upon 8

Answer 1

Step-by-step explanation:

let the number that should be subtracted be x then,

(-9/14)-x=11/8

-x=11/8+9/14

-x=(77+36)/56

-x=113/56

x= -113/56

for check,

-9/14-(-113/56)

= (-36+113)/56

=77/56

=11/8

Answer 2

Let the number that subtracted from -9/14=x

As per the question,

(-9/14)-x=11/8

=>-x=11/8+9/14

=>-x=(77+36)/56 (as the lcm of 8and 14=56)

=>-x=113/56

=>x=-113/56

VARIFICATION

-9/14-(-113/56)

=-9/14+113/56

=(-36+113)/56

=77/56=11/8 (Proved) (Ans.)
