If Kiyan spends 15% of his day in science class, and he spends 45 minutes in science class, we can calculate the total time he spends in school.
Let's denote the total time he spends in school as T minutes.
Since Kiyan spends 15% of his day in science class, this means that 45 minutes is equal to 15% of his total school day.
So, we can set up the equation:
0.15 * T = 45
To solve for T, we divide both sides of the equation by 0.15:
T = 45 / 0.15
T = 300
Therefore, Kiyan spends 300 minutes in school.
