2. Divide this result by denominator of the fraction: 378/4 = 94.5
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 378/2 = 189
   • 4/2 = 2
4. Which gives: 189/2

Since 189/2 is an improper fraction, the result could also be expressed as a mixed number: 94 1/2

How does it work?

The principle behind finding a fraction of a number, such as 6/4 of 63, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{6}{4}=\frac{x}{63}$ (where x represents 6/4 of 63)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $6\times 63=4x$
2. Which gives: $378=4x$
3. Divide both sides by 4 to isolate x: $\frac{378}{4}=\frac{4x}{4}$
4. Which gives the result: $\frac{378}{4}=x$ (or $\frac{189}{2}=x$)

Thus, 6/4 of 63 is equal to 189/2 (or 94.5 in its decimal form).
