In a week, a student exercise 2 hours at school and another 1/4 of an hour at home.
The total exercise of the students came plain soccer
The total hour a student exercise both home and school is
2 + 1/4
Our LCM is 4
4x2/1 + 4*1/4 /4
8 + 1 / 4
9/4 hours
A student exercise a total of 9/4 hours in a week
If one student exercise a total of 9/4 hours in a week then how many hours will 16 students exercise in a week
Mthematically,
1 student ========= 9/4 hours
16 students ======= x hours
Introduce cross multiplication
1 * x = 16 x 9/4
x = 16 x 9/4
x = 144/4
x = 36 hours
Therefore, 16 students exercise a total of 36 hours in a week
The answer is 36 hours
x = 144 / 4 hours
