sam makes some bread rolls. He gives 2/5 of the bread rolls to his neighbor and 4/9 of the remainder to his cousin. He has fifte

FinnZ [79.3K]

Neighbor: 2/5(x) 
Remainder = x - 2/5(x) = 3/5(x) 
Cousin = 4/9 * 3/5(x) = 4/15(x) 

x - 2/5(x) - 4/15(x) = 15 
x - 6/15(x) - 4/15(x) = 15 
x - 10/15(x) = 15 
(15x - 10x) = 225 
5x = 225 
x = 225/5 = 45 

Therefore, he made 45 rolls
