Answer :
Answer:
43.75% students were participated last year.
Step-by-step explanation:
We have been given that last year 7/16 of all students at a school participated in the science fair.
Let us suppose the total number of students were x. Then, number of students participated last year is given by
[tex]\frac{7}{16} x[/tex]
Hence, the percentage of the students participated last year is given by
[tex]\%=\frac{\frac{7}{16}x }{x} \times 100\\\\\%=\frac{7}{16}\times 100\\\\\%=43.75\%[/tex]
Therefore, 43.75% students were participated last year.
