Question

91 is 10% of what number?

Explanation:

Step1: Define the variable

Let the number we are looking for be \( x \). We know that \( 10\% \) of \( x \) is 91. Mathematically, \( 10\% \) can be written as \( 0.1 \) or \( \frac{10}{100} \). So we can set up the equation: \( 0.1x = 91 \) (or \( \frac{10}{100}x = 91 \)).

Step2: Solve for \( x \)

To solve for \( x \), we divide both sides of the equation \( 0.1x = 91 \) by \( 0.1 \). So \( x=\frac{91}{0.1} \). Calculating \( \frac{91}{0.1} \), we know that dividing by \( 0.1 \) is the same as multiplying by 10, so \( 91\times10 = 910 \).

Answer:

910
