What is 9/6 of 7?

How to calculate 9/6 of 7?

1. Multiply the whole number by the numerator of the fraction: 7 × 9 = 63
2. Divide this result by denominator of the fraction: 63/6 = 10.5
3. Simplify by dividing both the numerator and denominator by their GCD (3):
   • 63/3 = 21
   • 6/3 = 2
4. Which gives: 21/2

Since 21/2 is an improper fraction, the result could also be expressed as a mixed number: 10 1/2

How does it work?

The principle behind finding a fraction of a number, such as 9/6 of 7, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{9}{6}=\frac{x}{7}$ (where x represents 9/6 of 7)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $9\times 7=6x$
2. Which gives: $63=6x$
3. Divide both sides by 6 to isolate x: $\frac{63}{6}=\frac{6x}{6}$
4. Which gives the result: $\frac{63}{6}=x$ (or $\frac{21}{2}=x$)

Thus, 9/6 of 7 is equal to 21/2 (or 10.5 in its decimal form).
