Question

Three out of four students in a school said they would vote for nuncio for class president. Predict how many of the 340 students would vote for nuncio

Answer 1

3/4 = x / 340....3 to 4 students = x to 340 students
cross multiply
(4)(x) = (3)(340)
4x = 1020
x = 1020/4
x = 255 <==

or this way.....

3 out of 4 students.....3/4 = 75%
so 75% of 340 = 0.75(340) = 255 <=
