Question

what must be subtracted from -9÷14 to get 11÷18

Answer 1

so, your answer is-79/63

Answer 2

We have the given number as - 9÷14
We can write this in the fractional form in following ways :-

$\frac{( - 9)}{14}$

Now,
We have to make this number as 11÷18
So,
Converting this into fractional form we get the following :-
$\frac{11}{18}$

Also,

the number has to be obtained by subtracting.

so let the number which is to be subtracted be x. so this means that the given number subtracted by X will yield us the result as 11/18.

So,

representing the equation graphically :-

$\frac{( - 9)}{14} - x = \frac{11}{18} \\ \\ x = \frac{ ( - 9) }{14} - \frac{11}{18} \\ \\ x = \frac{18( - 9) - 11(14)}{18 \times 14} \\ \\ x = \frac{ - 162 - 154}{252} \\ \\ x = \frac{ - 316}{252} \\ \\ x = ( - 1.2539683)$

So,
the following numbers in a fractional form or in the decimal form can be subtracted from the given number to obtain the result
