Answer:
90%
Step-by-step explanation:
We are told that 9/10 of alien races think invading Earth is a bad idea.
To find the percent of alien races that think invading Earth is a bad idea we will have to find 9 is what percent of 10.
[tex]\text{The percentage of alien races that think invading Earth is a bad idea}=\frac{9}{10}\times 100[/tex]
[tex]\text{The percentage of alien races that think invading Earth is a bad idea}=9\times 10[/tex]
[tex]\text{The percentage of alien races that think invading Earth is a bad idea}=90[/tex]
Therefore, 90% of alien races think invading Earth is a bad idea.
