What is 2/8 of 4?

How to calculate 2/8 of 4?

1. Multiply the whole number by the numerator of the fraction: 4 × 2 = 8
2. Divide this result by denominator of the fraction: 8/8 = 1
3. Simplify by dividing both the numerator and denominator by their GCD (8):
   • 8/8 = 1
   • 8/8 = 1
4. Which gives: 1/1

How does it work?

The principle behind finding a fraction of a number, such as 2/8 of 4, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{8}=\frac{x}{4}$ (where x represents 2/8 of 4)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 4=8x$
2. Which gives: $8=8x$
3. Divide both sides by 8 to isolate x: $\frac{8}{8}=\frac{8x}{8}$
4. Which gives the result: $\frac{8}{8}=x$ (or $\frac{1}{1}=x$)

Thus, 2/8 of 4 is equal to 1/1 (or 1 in its decimal form).
