To determine the number that makes the equation [tex]\(\frac{9}{8} = \square \times \frac{1}{8}\)[/tex] true, we need to isolate the unknown number, [tex]\(\square\)[/tex].
We start by recognizing that both sides of the equation contain a fraction with a common denominator of 8. Therefore, we can eliminate the denominator by multiplying both sides of the equation by 8. This step simplifies the equation by removing the fractions:
[tex]\[
8 \times \frac{9}{8} = \square \times \frac{1}{8} \times 8
\][/tex]
Simplifying both sides:
[tex]\[
9 = \square
\][/tex]
Therefore, the number that makes the equation true is:
[tex]\[
\square = 9
\][/tex]
So the answer is [tex]\(9\)[/tex].
