Given:
There are between 24 and 40 students in a class.
The ratio of boys to girls is 4:7
To find:
The number of students in the class.
Solution:
Let the number of boys are girls are 4x and 7x respectively, where, x must be a positive integer because number of boys and girls is always a positive integer. Then, the total number of students is
It means total number of students is multiply of 11.
Multiples of 11 are 11, 22, 33, 44, ... . So, multiples of 11 between 24 and 40 is 33.
Therefore, the total number of students in the class is 33.
Answer: -15x - 23

If you were working with a flat rectangle and you were given the diagonal,
you'd want to use the Pythagorean theorem to choose two sides whose
squares would add up to the square of the diagonal.
It works exactly the same with a 3-D box. We need three dimensions for
the box, whose squares add up to the square of the diagonal between
opposite corners. That's (4)² = 16.
So (L)² + (W²) + (H²) = 16 . From there, you're completely free to pick any
numbers you want, just as long as their squares add up to 16. There are
an infinite number of possibilities. Here are a few:
1 x 1 x √14
1 x 2 x √11
2 x 2 x √8
2 x 3 x √3
1 x 3 x √6
