Answer:
90.
Step-by-step explanation:
Let x be our required number.
We are asked to find the number that is 10 times as much as 900.
10 times the number would be \(10x\).
We can represent our given information in an equation as:
\(10x=900\)
Let us solve for x.
\(\frac{10x}{10}=\frac{900}{10}\)
\(x=90\)
Therefore, 90 is 10 times as great as 900.
