Answer: True
Step-by-step explanation:
Given: The ratio of the number of boys to the number of girls at Liam's school is 4:5.
There are 270 students at his school.
Then, Total boys = [tex]\dfrac{4}{4+5}\times270=\dfrac{4}{9}\times270=120[/tex]
Total girls =[tex]\dfrac{5}{4+5}\times270=\dfrac{5}{9}\times270=150[/tex]
Clearly, (Number of girls) > (Number of boys)
Difference = (Total girls) - (Total boys)
= 150-120
= 30
So, Statement 3: "There are exactly 30 more girls than boys". is absolutely true.
