What is 2/2 of 77?

How to calculate 2/2 of 77?

1. Multiply the whole number by the numerator of the fraction: 77 × 2 = 154
2. Divide this result by denominator of the fraction: 154/2 = 77
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 154/2 = 77
   • 2/2 = 1
4. Which gives: 77/1

How does it work?

The principle behind finding a fraction of a number, such as 2/2 of 77, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{2}=\frac{x}{77}$ (where x represents 2/2 of 77)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 77=2x$
2. Which gives: $154=2x$
3. Divide both sides by 2 to isolate x: $\frac{154}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{154}{2}=x$ (or $\frac{77}{1}=x$)

Thus, 2/2 of 77 is equal to 77/1 (or 77 in its decimal form).
