Question

Can someone please help with this urgent help required , Thanks you very much in advance

Answer

LCM of 9 and 15 -> 45

45 ÷ 15 = 3

45 ÷ 9 = 5

So every 45 cm, there were 3 flags, and (5 – 1) = 4 photos

[Wall – 9cm(1) – photo1 – 9cm(2) – photo2 – 9cm(3) – photo3  – 9cm(4) – photo4 – 9cm(5) – Wall]

Every 45 cm, there was 1 more photo than flag.

To have 19 more photos, the wall needed to be (45 × 19) = 855 cm = 8.55 m
