Jawab:

16%

Penjelasan dengan langkah-langkah:

Percentage means a number or ratio expressed as a fraction of 100.

N% = N/100

100% = 100/100 = 1

Given a fraction of a/b, its equivalent percentage is:

(a/b × 100)% = (100a/b)%

Or, if the denominator (b) is a factor of 100, it is easier to calculate as follows.

(a/b × 100)% = (a × 100/b)%

We want to express 4/25 as a percentage.

4/25 = 4/25 × 100%

        = (400/25)%

        = 16%

Or

4/25 = 4/25 × 100%

.... (occupying commutative law because 25 is a factor of 100)

        = (4 × 100/25)%

        = (4 × 4)%

        = 16%

The latter is easier, I think.

∴  Conclusion:

If we express the fraction of 4/25 as a percentage, the result is 16%.
