The two strands of Decorative light will shine at same time after every 15 seconds.
<h3>What is defined as the Highest common factor?</h3>
- The greatest of all their common factors is the Highest Common Factor (HCF) of more than one number.
- As a result, it is also known as the greatest common factor (GCF).
- There isn't an exact formula for determining the greatest common factor of two numbers.
- However, when considering prime factorization, we can write a statement that aids in evaluating the greatest common factor of more than one number.
The stated condition are-
The light strand one change color every 30 seconds.
The light strand second change color every 45 seconds.
Prime factorization of both number are;
30 = 2×3×5
45 = 3×3×5
The numbers with highest power are;
HCF(30, 45) = 3×5 = 15.
Thus, the time after which both the light strands will change colour at the same time is 15 seconds.

Hei dere!
So this is how I learned it:
18 x
---- = -------
60 100
Cross cancel it:
60x=1800
x=30%
Hope I helped!

Answer:
I've been trying to figure this out with out a chart and i keep confusing myself
Step-by-step explanation:
nothing
<span>8x + 10 - 5x = 15
3x + 10 = 15
3x = 5
x = 5/3
hope it helps</span>
