Faith earned 1/3 of her allowance from washing the dishes and 1/6 of her allowance from cleaning her room. How much of Faith $36 allowance was not earned from washing the dishes or cleaning room?

1/6=$6
1/3=$12=
$18$36=
$18 or 1/2 
First find out how much of her allowance she earned washing dishes and cleaning her room:
(1/3)+(1/6) (Find LCD)
=(2/6)+(1/6)
=3/6
=1/2
So if 1/2 of her allowance is earned washing dishes and cleaning her room, then the other 1/2 of her allowance is earned doing other things. So:
(1/2)(36)=$13.00 
Sorry, hit the wrong key:
(1/2)(36)=$18.00
