Step-by-step explanation:
It's kinda hard to explain... I'd need more time to be sure, sorry. When's this due? Can you send a bigger picture and can I have about 10 more mins to solve, give or take?
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
The smaller share is 2/(2+3)*185 g = 74 g.
The larger share is 185 -74 g = 111 g.
