To determine what number 43 is 31% of, let's perform the following steps:
1. Convert the percentage to a decimal:
The percentage given is 31%. To convert this to a decimal, we divide by 100:
[tex]\[
31\% = \frac{31}{100} = 0.31
\][/tex]
2. Set up the equation:
Let [tex]\( x \)[/tex] be the unknown whole number that we are trying to find. According to the problem, 43 is 31% of [tex]\( x \)[/tex]. In mathematical terms, this can be written as:
[tex]\[
0.31x = 43
\][/tex]
3. Solve for [tex]\( x \)[/tex]:
To isolate [tex]\( x \)[/tex], we divide both sides of the equation by 0.31:
[tex]\[
x = \frac{43}{0.31}
\][/tex]
4. Calculate the result:
Performing the division gives:
[tex]\[
x \approx 138.70967741935485
\][/tex]
So, 43 is approximately 31% of 138.71.
