the HESI a2 will have a lot of word
problems on it so you need to be
prepared here's one example of a word
problem that you may encounter when
taking the Hesse your supervisor
instructs you to purchase 240 pens and
six staplers for the nurse's station
pens are purchased in sets of six for
two dollars and thirty-five cents per
pack staplers are sold in sets of two
for $12.95
how much will purchasing these products
cost well first let's break it up
because there's a lot of information
going on here
let's sit separate this into our pens
and our staplers and you can't just buy
these pens individually so first let's
figure out how many packs we're going to
have to buy we need 240 pens but we're
going to buy them in packs of six or
sets of six so divided by six means
we're going to end up needing 40 packs
of pins we have to buy 40 packs of pens
and each one cost two dollars and 35
cents so 40 packs times two dollars and
35 cents means we're going to spend
ninety four dollars just on our pens now
let's move to staplers the staplers we
need let's see and they're purchased in
sets of two for $12.95 and we need six
of those so first we'll figure out how
many staplers we need to buy six or how
many packs six divided by two is three
so we need to buy three sets of staplers
and each one of those costs $12.95 so
three times $12.95 is thirty-eight
dollars and 85 cents
finally we just need to add those two
totals together to get our total for our
pens and staplers so 94 plus 38 dollars
and 85 cents is a hundred thirty-two
dollars and 85 cents that would be your
total for all your pens and staplers
there's one example of a word problem
that you might encounter when taking the
HESI you will need to have some basic
math skills for the HESI a2 one of those
math skills would be finding the
reciprocal of a number so here we have
an example where we're going to find the
reciprocal of six first we need to know
what the word reciprocal means
reciprocal just means the inverse of a
number or the flip of a number so six
can also be written as 6 divided by 1
and then the reciprocal would just be
the flip of that or just 1 over 6 so 6
over 1 and 1/6 are reciprocals of each
other
therefore the reciprocal of 6 is 1/6
there's one example of how to find the
reciprocal of a number which you might
need to know when you take the HESI you
will need to know how to work percent
problems for the HESI a2 so here's an
example of a percent problem you could
see when you take the HESI 25% of 400
there are a couple ways you can look at
this one is that 25% is just 1/4 so it's
1/4 of 400 100 you could also change
your percent either into a fraction or
into a decimal 25 percent as a fraction
is 25 hundredths
because percent literally means her or
divided by 100
that's the cent part 100 which you could
simplify to 1/4 and you could write 25
percent as a decimal by simply taking
the decimal in 25 percent and moving it
two places to the left so it's 25
hundredths
just like the fraction 25 hundredths
once you've done that then you need to
take either your fraction or your
decimal and multiply it times 400
because the word of means to multiply so
in this case really using the fraction
would be easier because 1/4 times 400 is
easier to calculate you can either cross
cancel and simplify first or you can
multiply first by just multiplying
straight across
1 times 400 is 400 4 times 1 is 4 and
then you divide 400 divided by 4 is 100
so either way you work it you get that
25 percent of 400 is 100 and there you
have an example of a percent problem
that you might see when you take the
HESI you will need to have a good
understanding of percentages when taking
the heads EA 2 so here we have an
example problem of something you might
see whenever you take the HESI which of
the following percentages is equal to 45
hundredths it's really helpful if you
know how to say your decimal like this
one 45 hundredths because being able to
say this decimal correctly will help you
write it as a fraction more easily it's
45 hundredths which then makes turning
it into a percent even easier because
what percent literally means
is divided by 100 so this is 45% another
way to change a decimal into a percent
is to simply take the decimal and move
it two places to the right so 45
hundredths is equal to 45 percent and
there you have an example problem of a
percent that you might encounter on the
heavy you need to be prepared to do a
lot of word problems on the HESI a2 here
I have one example of a type of word
problem that you could encounter when
you take the HESI a roast was cooked at
325 degrees in the oven for 4 hours the
internal temp temperature rose from 32
degrees Fahrenheit to 145 degrees
Fahrenheit what was the average rise in
temperature per hour temperature per
hour tells us well it's almost all the
information we need and this average
rise is important too but this part
tells us how to set it up so it's
temperature per hour and then you can
even see that in the answer choices they
all have a temperature divided by one
hour that's a unit rate and then this
right here tells us what temperature
we're trying to find we need our
numerator needs to be the rise how much
the temperature rose in our roast and it
rose from 32 degrees to 145 degrees so
to find that rise we need to subtract
145 degrees minus 32 degrees so this
will give us our
rise in temperature divided by the
number of hours 145 - 32 is 113 degrees
Fahrenheit divided by 4 hours now on the
HESI you will have a calculator
accessible to you so if you just type in
113 divided by 4
you'll get 28 and 25 hundredths degrees
Fahrenheit per hour so that answer would
be answer B there you have one example
of a word problem that you may encounter
when you take the heavy
you
