Question

7. Which rational number should be added to
-2/-5to get 9/3​

Answer 1

Answer:

$\frac{13}{5}$

Step by Step:

the standard form of -2/-5

$= \frac{ - 2 \times - 1}{ - 5 \times - 1} = \frac{2}{5}$

According to question:

$\frac{2}{5} + x = \frac{9}{3 }$

$= \: \: \: \: \ x = \frac{9}{3} - \frac{2}{5}$

$= \: \: \: \: x = \frac{45 - 6}{15}$

$= \: \: \ \: \ x = \frac{39}{15}$

$= \: \: \: \: x = \frac{13}{5}$

So, 13/5 is added to -2/-5 to get 9/3.
