What is 2/4 of 100?

How to calculate 2/4 of 100?

1. Multiply the whole number by the numerator of the fraction: 100 × 2 = 200
2. Divide this result by denominator of the fraction: 200/4 = 50
3. Simplify by dividing both the numerator and denominator by their GCD (4):
   • 200/4 = 50
   • 4/4 = 1
4. Which gives: 50/1

How does it work?

The principle behind finding a fraction of a number, such as 2/4 of 100, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{4}=\frac{x}{100}$ (where x represents 2/4 of 100)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 100=4x$
2. Which gives: $200=4x$
3. Divide both sides by 4 to isolate x: $\frac{200}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{200}{4}=x$ (or $\frac{50}{1}=x$)

Thus, 2/4 of 100 is equal to 50/1 (or 50 in its decimal form).
