Question

What must be added to 15 8/13 to get 18 3/26.

The answer must be 5/2
Solve the sum

Answer 1

Solution :

Let The other number be x .

$\rm⇢ \: \: x + 15 \frac{8}{13} = 18 \frac{3}{26}$

$\rm⇢ \: \: x + \frac{203}{13} = \frac{471}{26}$

$\rm⇢ \: \: \frac{13x + 203}{13} = \frac{471}{26}$

$\rm⇢ \: \: 13x + 203 = \frac{471}{2}$

$\rm⇢ \: \: 2(13x + 203) = 471$

$\rm⇢ \: \: 26x + 406 = 471$

$\rm⇢ \: \: 26x = 471 - 406$

$\rm⇢ \: \: 26x = 65$

$\rm⇢ \: \: x = \frac{65}{26}$

$\rm⇢ \: \: x = \frac{5}{2}$

FINAL ANSWER :

The Other Number is 5/2 .
