What is 1/1 of 12?

How to calculate 1/1 of 12?

1. Multiply the whole number by the numerator of the fraction: 12 × 1 = 12
2. Divide this result by denominator of the fraction: 12/1 = 12

How does it work?

The principle behind finding a fraction of a number, such as 1/1 of 12, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{1}=\frac{x}{12}$ (where x represents 1/1 of 12)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 12=1x$
2. Which gives: $12=1x$
3. Divide both sides by 1 to isolate x: $\frac{12}{1}=\frac{1x}{1}$
4. Which gives the result: $\frac{12}{1}=x$

Thus, 1/1 of 12 is equal to 12/1 (or 12 in its decimal form).
