11. 2/5 = 40/100 = 40%      12. 29/50 = 58/100 = 58%

Step-by-step explanation:

To convert the given fraction to a fraction of 100, cross-multiply and divide.

2 × 100 = 200 / 5 = 40

Then, whenever you have a number over 100, all you need to do to get the percentage is find the numerator and add a percent sign at the end of the number.

40 ⇒ 40%

Repeat this with the second question.

29 × 100 = 2900 / 50 = 58 ⇒ 58%
