Math on HESI A2?

This book has everything you need to know for the math portion. Basic addition, subtraction, division, multiplication, fractions, ratios. It really does help. I made a C in College algebra but got a 96% on the math portion of the test thanks to this book.

Definitely get the book. It will help a lot. Go through all the practice problems in the book. You can use a calculator on screen during the test so use a calculator when doing the practice problems. I just took it today and got 100 on the math section.

Im having a similar problem.. Ive been reading a lot that there are a bunch of "ratio" questions.. Can someone explain to me what that would consist of? I know how to solve a proportion, but what is a ratio question? Is it just like changing a decimal or fraction into ratio form?

A ratio is a comparison used to figure drug doses. An example would be one tablet =325 mg. The md orders 650 mg. That ratio would be x tablet = 650 mg. You would then put the two ratios together to solve for x.

325 mg : 1 tablet = 650 mg : x tablet

Multiply outer and inner and you get

325 mg x tablet= 650 mg

Divide both sides by 325 mg tablet so that x stands alone and you get

X = 2 tablets

Thanks but I thought that process would be solving a proportion?

Okay I think ive got it now. A proportion is just making two ratios equal to each other. #duh lol Thank You!

Just an FYI. I knew i was right. That is a Proportion question. The ratio questions were more like 7 of 8 students are girls. How many of the (random number) of students are girls.
