Question

Divide the sum
of -1/2 and-4/9 by their difference​

Answer 1

Answer:

17

Step-by-step explanation:

Here the sum of -1/2 and -4/9 is

$\frac{ - 1}{2} + ( \frac{ - 4}{9} ) = \frac{ - 9 - 8}{18}$

$\frac{ - 17}{18}$

The difference of -1/2 and -4/9 is

$\frac{ - 1}{2} - ( \frac{ - 4}{9} ) = \frac{ - 9 + 8}{18} = \frac{ - 1}{18}$

Now, the sum by difference

$\frac{ - 17}{18} \div \frac{ - 1}{18}$

$\frac{ - 17}{18} \times \frac{18}{ - 1}$

So the answer is 17

Answer 2

Answer:

Heya mate!!

Here's your answer

$sum \: = \frac{ - 1}{2} + ( \frac{ - 4}{9} )$

$\frac{ - 1}{2} - \frac{4}{9}$

$\frac{ - 9 - 8}{18} = - \frac{17}{18}$

$difference = \frac{ - 1}{2} - \frac{ - 4}{9}$

$- \frac{1}{2} + \frac{4}{9}$

$\frac{ - 9 + 8}{18} = \frac{ - 1}{18}$

$\frac{sum}{difference} = \frac{ - 17}{18} \times \frac{18}{ - 1}$

$answer = 17$
