Question

if 1.27 bar =x/y then find x+y​

Answer 1

Answer:

25

Step-by-step explanation:

1.27 bar

= 1  27/99

= 126/99

= 14/11

14+11 = 25

Answer 2

$\huge \blue{\boxed{ \brace{ \overbrace{\underbrace{ \mathbb{ANSWER:-}}}}}}$

$\sf 1. \overline{27} \; in \: x/y \: form$

_________________________________

Let's consider $a$ as $\sf 1. \overline{27}$

Then $100a$ = $\sf 127. \overline{27}$

Subtracting $a$ from $100a$ will give,

$100a-a=127. \overline{27} - 1. \overline{27}$

$99a = 126$

$a = \cancel{\dfrac{126}{99}} = \dfrac{14}{11}$

$a = \dfrac{14}{11}$

______________________

$\sf 1. \overline{27} \: in \: x/y \: form = \dfrac{14}{11}$

$\dfrac{x}{y} = \dfrac{14}{11}$

$\sf x+y = 14+11 = 25$

x + y = 25

Hope it helps
