17 is 43% of ??
The trick is to turn that english sentence above into a MATHMATICAL (think equation) sentence. So here are 4 things you need to know about the sentence above:
"43%" = 43/100 = .43
"is" = equal sign
"of" = multiply
"??" = X
Therefore
17 is 43% of ??
17 = .43 * X
Solve the equation:
(1/.43) * 17 = (.43 * X) * (1/.43)
39.53 = X

Write it down as a simple equation and let "x" be the unknown figure
We get, 17= 43% of x
or, 17= 43/100 of x
or, 17 x 100 = 43x
or, x = 1700/43 = 39.534883
or, x = 40 (rounded to the nearest digit)

If you cross multiply, saying 17/43 = x/100, I got x = 39.53488 as an answer

Ok, 43% is 43/100, so (17/X) equals (43/100). You cross multiply and you get (43)(X) equals 1700. Then you divide 1700 by 43, and you get X equals 39.534. So 17 is 43 percent of 39.534, because 17/39.534 equals .43.
Hope that helps.

Its 39.53 (correct to two places of decimal).
When you find % symbol mentally change it into /100. That means, 43 percent = 43/100.
Now, from your question, it is clear that 17= 43/100 * ( unknown number).
So the ( unknown number) = 17 * 100/43 =1700/43 = 39.53

Make it into a proportion.
43/100 (or 43%) = 17/x
Now cross multiply.
43 17
-- = --
100 x
17 times 100= 1700
43 times x= 43x
1700=43x
1700/43=x
x=39.534...
Its a very long number.

Put it in equation form
Let y be the answer
So 43% of y = 17
43/100 x y =17
y =(17 x 100)/43
y = 1700/43
y =39.53
So 43% of 39.53 is 17.

First divide 17 from 43 the answers will be: 0.3953 so if 0.3953 is the 43rd part of 17 then Multiply 0.3953 by 100 after multiplication the answer will be 39.5 and this will be answer.

normally the question is posed x% of y is z. in your question you're given 43% of y is 17. so, 'of' also means multiplication. so you could rewrite the question as 43/100 x y = 17. next, you make y the subject of the formula and it becomes
43y/100=17
43y= 17 x 100
43y= 1700
y= 1700/43
y= 39.535
