A rain tree and bougainvillea bush are planted at a common point A along the
pavement. Find the distance from A to the next point where a rain tree and
bougainvillea bush are planted together.


Please help with this question.

Answer 1

120 m

Explanation:

LCM of 1.6 and 15 will give us the distance

Put 1,6 and 15 in same format:

• 16/10= 2*2*2*2/10
• 150/10= 2*3*5*5/10

LCM= 2*2*2*2*3*5*5/10= 120 m

So the next point is 120 m apart
