Answer 1

$\huge{\pink{\bold{\boxed{\ulcorner{\star\:Solutions:\: \star}\urcorner}}}}$

School has 8 period.
Each period = 45 minutes

If school has 9 period in a day
Then,
Let the duration of each period be x

A/q
8×45 = 9×x
=> 9x = 360
=> x = 360/9 = 40

Hence,
If school has 9 period in a day then each period duration
$\huge {\bold { = ~40 minutes. }}$


Now,
If each period = 36 minutes
Then,
Let the period be x

A/q
36×x = 8×45
=> 36x = 360
=> x = 360/36 = 10

Hence,
If period is 36 minutes then there are
$\huge {\bold {=~10 periods}}$
