Question

what should be added to -2/7 to get 1 ?​

Answer 1

Answer:

Let x be any number.

According to given statement, we get

x + (-2/7) = 1

x - 2/7 = 1

x. = 1 +2/7

x. = 9/2

= 4.5 Ans.

Answer 2

$solution$

$let \: the \: required \: number \: be \: x.$

$x + \frac{ - 2}{7} = 1$

$x = \frac{1}{1} - \frac{ - 2}{7}$

LCM of 1 and 7 is 7.

$x = \frac{7 - ( - 2)}{7}$

$x = \frac{9}{7}$

$therefore \: required \: number \: is \: \frac{9}{7}$

$proof \:$

$\frac{9}{7} + \frac{ - 2}{7}$

LCM of 7 and 7 is 7.

$= \frac{9 + ( - 2)}{7}$

$= \frac{7}{7} = 1$

hence verified
