What is 6/9 of 5?

How to calculate 6/9 of 5?

1. Multiply the whole number by the numerator of the fraction: 5 × 6 = 30
2. Divide this result by denominator of the fraction: 30/9 = 3.3333333333333
3. Simplify by dividing both the numerator and denominator by their GCD (3):
   • 30/3 = 10
   • 9/3 = 3
4. Which gives: 10/3

Since 10/3 is an improper fraction, the result could also be expressed as a mixed number: 3 1/3

How does it work?

The principle behind finding a fraction of a number, such as 6/9 of 5, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{9}=\frac{x}{5}$ (where x represents 6/9 of 5)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 5=9x$
2. Which gives: $30=9x$
3. Divide both sides by 9 to isolate x: $\frac{30}{9}=\frac{9x}{9}$
4. Which gives the result: $\frac{30}{9}=x$ (or $\frac{10}{3}=x$)

Thus, 6/9 of 5 is equal to 10/3 (or 3.3333333333333 in its decimal form).
