Question

____ + 2/18 = 1, please help

Answer 1

Answer:

Let the number be x

that is

$x + \frac{2}{18} = 1 \\ \frac{18x + 2}{18} = 1 \\ 18x + 2 = 1 \times 18 = 18 \\ 18x = 18 - 2 = 16 \\ x = \frac{16}{18} = \frac{8}{9}$

Value of x=8/9

Therefore the number is 8/9

Let's check whether it's correct or not

$\frac{8}{9} + \frac{2}{18} = 1 \\ \frac{144 + 18}{162} = 1 \\ \frac{162}{162} = 1 \\ 1 = 1$

L.H.S=R.H.S

hence verified

Answer 2

Answer:

$x + \frac{2}{18} = 1 \\ (lcm = 18) \\ \frac{18x + 2}{18} = 1 \\ 18x + 2= 18 \\ 18x = 18 - 2 \\ 18x = 16 \\ x = \frac{16}{18} \\ \\ x = \frac{8}{9}$
