Question

x/3+1=7/15 in maths class 8​

Answer 1

Answer:

-8/3

Step-by-step explanation:

x/3 = 7/15 - 1

x/3 = -8/15

x= -8/15 * 3

x= -8/3

Answer 2

$\implies$ $\dfrac{x}{3}$ + 1 = $\dfrac{7}{15}$

$\implies$ $\dfrac{x}{3}$ = $\dfrac{7}{15}$ - 1

$\implies$ $\dfrac{x}{3}$ = $\dfrac{7}{15}$ - $\dfrac{1}{1}$

• LCM of 15 and 1 is 15.

$\implies$ $\dfrac{x}{3}$ = $\dfrac{7\:-\:15}{15}$

$\implies$ $\dfrac{x}{3}$ = $\dfrac{-8}{15}$

$\implies$ x = $\dfrac{-8\:\times\:3}{15}$
