What is 1/6 of 9?

How to calculate 1/6 of 9?

1. Multiply the whole number by the numerator of the fraction: 9 × 1 = 9
2. Divide this result by denominator of the fraction: 9/6 = 1.5
3. Simplify by dividing both the numerator and denominator by their GCD (3):
   • 9/3 = 3
   • 6/3 = 2
4. Which gives: 3/2

Since 3/2 is an improper fraction, the result could also be expressed as a mixed number: 1 1/2

How does it work?

The principle behind finding a fraction of a number, such as 1/6 of 9, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{1}{6}=\frac{x}{9}$ (where x represents 1/6 of 9)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $1\times 9=6x$
2. Which gives: $9=6x$
3. Divide both sides by 6 to isolate x: $\frac{9}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{9}{6}=x$ (or $\frac{3}{2}=x$)

Thus, 1/6 of 9 is equal to 3/2 (or 1.5 in its decimal form).
