Answer:
11. 2/5 = <u>40</u>/100 = <u>40</u>% 12. 29/50 = <u>58</u>/100 = <u>58</u>%
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%
