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 [tex]10x[/tex].
We can represent our given information in an equation as:
[tex]10x=900[/tex]
Let us solve for x.
[tex]\frac{10x}{10}=\frac{900}{10}[/tex]
[tex]x=90[/tex]
Therefore, 90 is 10 times as great as 900.
