37 1/2% of _________ is 36, Please help show work I am really confused.

klio [65]

Before you start working on this problem, make sure you know
how to use a couple of the tools in your toolbox:

Tool #1: 37-1/2 percent means 0.375

Tool #2: In math problems, "of" almost always means "times".

====================================

Your question says

   "37-1/2 percent of blank is 36".

Translate it with your tools:

      0.375 times blank = 36 .

Divide each side by 0.375:     Blank = 36 / 0.375 .

Now grab your pencil or your calculator, and find the value of that
fraction (do the division). Blank is equal to the value of the fraction.

To check your answer (find out whether it's correct):

Do exactly what the question says.

Multiply (0.375) times (your answer). If you get 36,
then your answer is correct. If not, it's not.

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube

Dmitrij [34]

Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

$\frac{99}{2} (2x+98)=p^3 \\ \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}$

By substitution, we have that $p=33$ and $x=314$ .

Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>
