What is 2/1 of 100?

How to calculate 2/1 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: 200/1 = 200

How does it work?

The principle behind finding a fraction of a number, such as 2/1 of 100, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{1}=\frac{x}{100}$ (where x represents 2/1 of 100)

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

Thus, 2/1 of 100 is equal to 200/1 (or 200 in its decimal form).
