Each friend got 3 cookies

3 0

Answer: 3 cookies

Step-by-step explanation:

Let each friend get cookies  = x

If there are 7 friends in the picnic, then the cookies are eaten by friends = 7x

Since, after distributing the cookies 3 cookies left,

Thus, the total number of cookies = 7x + 3

But, the total number of cookies = 24

⇒ 7x + 3 = 24

⇒ 7x = 21

⇒ x = 3

Hence, one friend gets cookies = 3.

Convert 11.42424242 to a rational expression in the form a/b, where b=0
lutik1710 [3]
I think you mean b is not equal to 0.

We have that 11.424242... = 11 + 0.424242...
Now let x = 0.424242...
Then 100x = 42.424242...
Now 99x = 100x - x = 42 so 99x = 42 and therefore x = 42/99

Now we can simplify 42/99 to 14/33

Now combining this we get 11.424242... = 11 + 14/33
= 363/33 + 14/33 = 377/33
