Question

what number should be subtracted from-8 by 15 so as get m 5 by 6​

Answer 1

Answer:

Step-by-step explanation:

Let the required number should be subtracted be x. Then ,

according to question ,

-8/15 - x = -5/6

=> - x = -5/6 + 8/15

=> - x = -25 + 16/30

=> - x = -9/30

=> x = 9/30

Answer 2

Step-by-step explanation:

let the number subtracted from -8 be X

so,

$\frac{ - 8}{15} - x = \frac{5}{6}$

$\frac{ - 8}{15} - \frac{5}{6 } = x$

LCM of 15 and 6 is 30

$\frac{ - 8 \times 5}{15 \times 2} - \frac{5 \times 5}{6 \times 5} = x$

$\frac{ - 40}{30} - \frac{25}{30} = x$

$\frac{ - 40 - 25}{30} = x$

$\frac{ - 65}{30} = x$

$\frac{ - 13}{6} = x$

so the number subtracted from-8 is -13/6
