What fraction of them are prime numbers ​

Answer 1

Natural numbers = 1,2,3,4,5,6,7,8,9,10,11,12,13,14 and 15

There are prime numbers = 1,3,5,7,11and 13.

So,

.

simplest form = 6/15 =3/5

Answer 2

Question ⤵️

Write all the natural numbers from 1 to 15

What fraction of them are prime numbers

Answer ⤵️

• Natural Numbers between 1 and 15

= 1, 2, 3, 4, 5, 6, 7, I, 9, 10, 11, 12, 13, 14, 15.

• Prime Numbers between 1 and 15

= 1, 3, 5, 7, 11, 13.

• Fraction of Prime Numbers in Natural Numbers

$= \huge \frac{no. \: of \: prime \: numbers}{no. \: of \: natural \: numbers}$

$= \huge \frac{6}{15}$

Cancelling the faction and making it in simplest form,

$\huge\frac{ \cancel{6}}{ \cancel{15}} = \frac{2}{5}$

$\huge \therefore \frac{2}{5}$

Answer:-

$\huge\frac{2}{5} \: \: \: is \: \: \: your \: \: \: answer$
