algebra question?

Question

ok well they are making our class do a middle school review.. and here is this really easy problem.. but i dont remember how to do it AT ALL.. so could you tell me how to do it please

27 is 36% of what number??

Answer 1

You have it set up perfectly. The easiest way to do percents is to say the problem out loud and then translate the words into algebra:

27
(27)

is
(=)

36%
(.36)

of
(*)

what number?
(x)

So the equation is:
27 = .36(x)

Solve for x by dividing both sides by .36.

This works for almost every percent problem, so make sure you get it!

Answer 2

Any form of the verb "to be" is an equals sign. "Of" means multiply. "%" means divide by 100. "What number" is a variable - let's use x. So the problem becomes

27 = 36/100 * x

x = 100 * 27/36 = 75

Answer 3

"is" means equal.

"of" means multiply.

"what number" means a variable.

You need to translate this to an equation.

27 = 36% * x

convert your percent to decimal or fraction:

27 = .36 * x

I'll let you solve from there.

Note that this problem can also be set up as a proportion.

is    %
-- = ----
of   100

This would look a lot better if they allowed formatting.

"is" in this case is 27
"%" is 36
"of" is the unknown

27   36
-- = ----
x   100

Again, I'll let you solve from there.

Answer 4

well. if your trying to find 27 is 36% of what number. it means that 27 is only 36% of something.

36 % = .36
27/.36 = 75

27 is 36% of 75

to check:

36% = .36
75 x .36 = 27

Answer 5

heyy you can turn that in into a really nice percent equation. remember: of means multiply [x].
so, is means equals.
27=0.36n
Let n=number.
36% translates to 0.36
27=0.36n
solve: divide each side by 0.36.
27 divided by 0.36 = 75.
respectively, you get;
75=n
75 is your number you were looking for.
remember, always remember the percent equation. it really helps :D ♥

you can check:
75 * 0.36 = 27
that works!!

good luck©™

Answer 6

the word "is" means equal and "of" means multiply. First, change 36% into a dicimel... so .36n=27. divide 27 by .36 and ull get your answer.

Answer 7

First change it to algebra form:

'is' becomes '='
'36%' becomes '0.36'
'of' becomes 'times' (as in multiplication)
'what number' becomes 'x'

So you get the formula:

27=0.36x

Divide 0.36 by 27 and you have your answer.

Answer 8

Make it into a formula:

27 = 0.36x

Can you solve for x now?
