   • 7/7 = 1
4. Which gives: 16/1

How does it work?

The principle behind finding a fraction of a number, such as 2/7 of 56, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{7}=\frac{x}{56}$ (where x represents 2/7 of 56)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 56=7x$
2. Which gives: $112=7x$
3. Divide both sides by 7 to isolate x: $\frac{112}{7}=\frac{7x}{7}$
4. Which gives the result: $\frac{112}{7}=x$ (or $\frac{16}{1}=x$)

Thus, 2/7 of 56 is equal to 16/1 (or 16 in its decimal form).
