Question

On the first day of school, 20 out of the first 25 students who entered the school were carrying a backpack. Based on this information, if 440 students were at school, how many students could be expected to be carrying a backpack?

A) 330
B) 352
C) 374
D) 396

Answer 1

The answer is B) 352.
20 out of 25 students means a ratio of 4:5.
Since the total number of students the next day is 440, we need to find 4:5::x:440.
Divide 440 by 5, multiply it with 4 and you'll get 352.

Hope this helps!

Answer 2

b) 352

Explanation:

352 students.

20 /25 = 4/ 5

440 × 4 /5 = 1760/5 = 352
