- Math ratio word problem -
**bobpursley**, Saturday, January 3, 2009 at 3:36pmRachal, I messed that up.

H/S=11/5 so 5H=11S

and 2S+12=H

From the first equation H=11S/5

putting that into the second.

2S+12=11S/5

multiplying both sides by 5

10S+60=11S

adding sixty to both sides and subtracting 11S from both sides.

-S=-60 or S=60

so H=11*60/5=132
