Question

What rational number should be substracted from -5/7 to get -9/14?​

Answer 1

Step-by-step explanation:

-5/7+x=-9/14

x=-9/14+5/7

x=-9/14+10/14

x= -1/14

Answer 2

Answer:

$rational \: no. \: should \: be \\ subtracted \: from \: \frac{ - 5}{7} to \: get \: \frac{ - 9}{14} \\ is \: \frac{ - 1}{14}$

Step-by-step explanation:

$let \: the \: no. \: be \: x \\ a/q,\\ (\frac{ - 5}{7} ) - x = \frac{ - 9}{14} \\ ( \frac{ - 5}{7}) + ( \frac{9}{14}) = x \\ \frac{ - 10 + 9}{14} = x\\ \frac{ - 1}{14} = x \\ x = \frac{ - 1}{14}$

$therefore \: rational \: no. \: should \: be \\ subtracted \: from \: \frac{ - 5}{7} to \: get \: \frac{ - 9}{14} \\ is \: \frac{ - 1}{14}$
