A school collected some information about the experience of its teachers. Here is what they found: What fraction of English teachers have at least 5 years of experience?

The fraction of English teachers who have at least 5 years of experience is [tex]\dfrac{11}{80}[/tex].
We want to calculate the number of teachers that have at least 5 years of experience, therefore, any teacher having experience of 5 years and more will come in this category,
Number of teachers having at least 5 years of experience
= Teacher having 5 to 10 years of experience
+ teachers having more than 10 years of experience
= 9 + 2 = 11
Total number of teachers = 80
[tex]\rm Fraction = \dfrac{\text{Number of teachers having at least 5 years of experience}}{\text{Total number of teachers}}[/tex]
[tex]\rm Fraction = \dfrac{11}{80}[/tex]
Hence, the fraction of English teachers who have at least 5 years of experience is [tex]\dfrac{11}{80}[/tex].
