What is 1/2 of 56?

How to calculate 1/2 of 56?

1. Multiply the whole number by the numerator of the fraction: 56 × 1 = 56
2. Divide this result by denominator of the fraction: 56/2 = 28
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 56/2 = 28
   • 2/2 = 1
4. Which gives: 28/1

How does it work?

The principle behind finding a fraction of a number, such as 1/2 of 56, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{2}=\frac{x}{56}$ (where x represents 1/2 of 56)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 56=2x$
2. Which gives: $56=2x$
3. Divide both sides by 2 to isolate x: $\frac{56}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{56}{2}=x$ (or $\frac{28}{1}=x$)

Thus, 1/2 of 56 is equal to 28/1 (or 28 in its decimal form).
