Write the prime no. from 12 to 15, and find the fraction of it.
A number greater than 1, with exactly two factors, 1 and itself, is defined as a prime number in mathematics. In other words, if a number cannot be divided into equal groups, then it is a prime number.
Answer: The prime number between 12 to 15 is 13 and the fraction is 1/4
Any whole number greater than 1 that is divisible only by 1 and itself, is defined as a prime number. We need to calculate the numbers that have only two factors from 12 to 15.
There are 4 whole numbers from 12 to 15 that are; 12, 13, 14, 15
Out of these 4 whole numbers, there is only one number 13 that has only two factors, therefore it is a prime number.
Now, the fraction of the prime number is calculated by dividing the numbers of prime numbers from 12 to 15 by the total number of whole numbers from 12 to 15.
Fraction = 1/4
