Question

what should be subtracted from minus 7 by 8 so as to get 5 by 12 ​

Answer 1

Answer:

let 1 no. be x

-7/8 -x =5/12

= -× = -5/12 +7/8

= - x = -10+21/24

= -× = + 11 / 24

= × = -11/24

Answer 2

Answer:

$= - \frac{7}{8} - x = \frac{5}{12} \\ = x = \frac{5}{12} + \frac{7}{8} \\ = x = \frac{10}{24} + \frac{21}{24} \\ = x = \frac{31}{24}$

Step-by-step explanation:

$take \: the \: lcm \: of \: the \: denominators \: so \: you \: will \: get \: the \: denominator \: as \: 24$
