在偶像大赛中，全校人数的 $\frac{7}{9}$ 决定投票。 共有 3 名参赛者，投给这些参赛者的票数按 $\frac{1}{3}:\frac{5}{6}:0.5$ 的比例分配。已知该校人数为 1440 名学生，计算投票给得票最多参赛者的学生人数。 答案 ... 名学生

1. Calculate the number of students who voted.

Number of voters
$=\frac{7}{9}\times 1440=1120$

2. Find the largest share of the votes using the ratio.

The ratio is
$\frac13:\frac56:0.5=\frac13:\frac56:\frac12$
Multiplying all parts by $6$,
$2:5:3$
The contestant with the most votes has $5$ parts out of $2+5+3=10$ parts.
$\frac{5}{10}\times 1120=560$
