i went and looked at my hesi book at the math ratios in it just to see if itd make me remember more of the ratios on the hesi test, so that i could help you out more. I can honestly say, if you know how to set up ratios, you are fine. As long as you know in the word problem that if it says "6 were $10.. how many were $25" its all set up like that. Just like if they say 1 in = 2.54 cm and they want 20 cm = how many inches -- then you know 1in/2.54cm = x(in)/20(cm) = 7.87 in --- that a proportion - just think about what they are asking you and you can set up any proportion thrown at you. Try out the hesi A2 app, there are tons of proportion word problems.
ex. "a plan for a house is drawn on a 1:40 scale (1 is the drawing, 40 is the actual house) - if the length of the living room on the drawing measures 4.5 inches, what is the actual length of the built living room. this is a proportion--- 1/40 = 4.5/X (bc 4.5 is the drawing it goes on top) so 4.5 X 40 = 180 inches (15 feet)
what is 35% of 70 is a proportion --- (of 70 always goes on the bottom) X/70 = 35%/100 = 24.5 (70 X 35 divided by 100)
how many pounds are there in 8 kilograms -- proportion - 2.2pouds/1kilogram = X/8kilograms (2.2 X 8) =17.6
if a train travels 270 miles in 3 hours, how far will it travel in 4.5 hours? 270miles/3hours = X/4.5hours (270 X 4.5 divided by 3) = 405

I need help with word problem ratios for the hesi. They are confusing me and if anyone has tips it would really help.
