Understanding each of these components is crucial to solving the problem and appreciating its wider significance.

Step-by-Step Calculation

Let's break down the calculation:

Simplify the Fraction: Before performing the multiplication, it's highly beneficial to simplify the fraction 144/360. Both the numerator and the denominator are divisible by common factors. Let's find the greatest common divisor (GCD).
- Factors of 144: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
- Factors of 360: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
The GCD of 144 and 360 is 72. Dividing both the numerator and the denominator by 72, we get:

144 ÷ 72 = 2 360 ÷ 72 = 5

That's why, 144/360 simplifies to 2/5.
Perform the Multiplication: Now, we can perform the multiplication:

2/5 x 110

This can be written as:

(2 x 110) / 5

2 x 110 = 220

220 / 5 = 44

That's why, the final answer is 44.

The Importance of Simplification

Simplifying the fraction before multiplication significantly reduces the complexity of the calculation. On the flip side, working with smaller numbers makes the process easier and minimizes the risk of errors. In this case, simplifying 144/360 to 2/5 made the multiplication significantly simpler, reducing the chance of calculation mistakes.
