one quarter means 1/4. 1/4 = 1/2 x 1/2 , so to easily find one quarter of 15 min:
1) you need to half (1/2) 15 min, which is 7min 30sec
2) you need to half this answer, which is 3min 30sec + 15 sec
which is 3min 45sec
WHY?
1/4 of 15min = 1/4 x 15min
= (1/2 x 1/2) x 15min
= 1/2 x (1/2 x 15min)
= 1/2 x (7min 30sec)
= (1/2 x 7min) + (1/2 x 30sec)
= (3min 30sec) +(15sec)
= 3min + (30sec + 15sec)
= 3min 45sec
