Step 2: Multiply the result by 100.

Multiply the decimal obtained in Step 1 by 100 to convert it into a percentage:

0.9286 × 100 = 92.86

Step 3: Round to the desired precision.

Simplifying the Fraction (Optional)

While not strictly necessary for the percentage calculation, simplifying the fraction before converting can sometimes make the division easier. Both 39 and 42 are divisible by 3:

39 ÷ 3 = 13 42 ÷ 3 = 14

So, 39/42 simplifies to 13/14. You can then perform the division:

13 ÷ 14 ≈ 0.9286

Multiplying by 100 still gives you approximately 92.86%.
