Question

the sum of money is shared among three brothers .the eldest brother recieves 7/13 of it and the second brother recieves 2/3,of the remainder .what fraction does the third brother recieves.

Answer 1

Answer:

2/13

Step-by-step explanation:

Eldest Brother Receives = 7/13

Second Brother Receives = 2/3 of the remainder

Let the Total Sum = X

Remainder after eldest son = 1 - 7/13

=1/1 - 7/13

LCM = 13

ie 13/13-7/13 = 6/13

So second son receives = 2/3 of 6/13

= 2/3 x 6/13

= 12/39

Therefore third son receives = 1 - 7/13 - 12/39

LCM = 39

ie 39/39 - 21/39 - 12/39

= 6/39 = 2/13
