What is 2/1 of 2?

How to calculate 2/1 of 2?

1. Multiply the whole number by the numerator of the fraction: 2 × 2 = 4
2. Divide this result by denominator of the fraction: 4/1 = 4

How does it work?

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

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

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

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