What fraction of numbers from 2 to 12 are composite numbers?
11​

Answer 1

Step-by-step explanation:

8/24 hours

fraction of how much he awake =16/24

we needed 8 hrs to sleep

Given rotten apple = 2/5

Total apples = 25

Hence number of rotten apple = 2/5 × 25

= 10

Since 10 apples are rotten, this means rest are good.

So good apples = 25 - 10 = 15

Hence, 15 apples are good

numbers from 2 to 12 = Prime number from these are = 2, 3, 5, 7, 11 Therefore, Total numbers = 11 Number of Prime numbers = 5 ∴ Fraction = / Prime numbers Numbers which have only 2 factors – 1 & the number itself Eg: 2, 3, 5, 7…….
