What is 2/4 of 41?

How to calculate 2/4 of 41?

1. Multiply the whole number by the numerator of the fraction: 41 × 2 = 82
2. Divide this result by denominator of the fraction: 82/4 = 20.5
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 82/2 = 41
   • 4/2 = 2
4. Which gives: 41/2

Since 41/2 is an improper fraction, the result could also be expressed as a mixed number: 20 1/2

How does it work?

The principle behind finding a fraction of a number, such as 2/4 of 41, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{4}=\frac{x}{41}$ (where x represents 2/4 of 41)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 41=4x$
2. Which gives: $82=4x$
3. Divide both sides by 4 to isolate x: $\frac{82}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{82}{4}=x$ (or $\frac{41}{2}=x$)

Thus, 2/4 of 41 is equal to 41/2 (or 20.5 in its decimal form).
