Answer 1

If blue=5/5*100=100%
If not blue=2/5*100=80%

Answer 2

Answer:  In first case, percentage of her blue jeans is 100% and in second case, the percentage of her blue jeans is 60%.

Step-by-step explanation:

Since we have given that

Total pairs of jeans Jenna has = 3

Number of blue jeans in it = 3

According to question, if he bought 2 more jeans of blue color,

Then, Total number of pairs of jeans = 5

Number of blue jeans = 5

So, percentage of her jeans which is blue now is given by

$\dfrac{5}{5}\times 100\\\\=100\%$

If 2 more jeans are not blue.

Total number of jeans = 5

Number of blue jeans = 3

So, percentage of her jeans which is blue now is given by

$\dfrac{3}{5}\times 100\\\\=3\times 20\\\\=60\%$

Hence, in first case, percentage of her blue jeans is 100% and in second case, the percentage of her blue jeans is 60%.
