Question

What should be subtract
from-12/13 to get 7/15?​

Answer 1

Answer:

5/24

Step-by-step explanation:

first we will make both denominators equal  

ok so  

7/-8 * 3/3= 21/-24

-13/12 * 2/2= -26/24

let the number be x

-21/24 -x = -26/24

so this is the equation  

so we need to solve for x  here  

x=-21/24 +26/24

x= 5/24

ok so the Answer is 5/24

Answer 2

Answer:

-271/195

Step-by-step explanation:

Let the number be x

Then, according to the question,

$-\frac{12}{13}$ $-x=\frac{7}{15}$

$x=-\frac{12}{13}-\frac{7}{15}$$x=-(\frac{12}{13} +\frac{7}{15} )$

Now taking the LCM,

$x=-(\frac{12*15}{13*15} +\frac{7*13}{15*13} )=-(\frac{180+91}{195} )$

$x=-\frac{271}{195}$

Therefore you have to subtract -271/195 from -12/13 to get 7/15
