To express units as a fraction you need to use a ratio and then simplify the fraction until its irreducible.

(36 minutes) x [ (1 hour) / (60 minutes) ] = 36/60 = 12/20 = 6/10 = 3/5

answer = 3/5 hour

Answer:

Hi, there!

What is 30/65 in simplest form?

30/65 simplified to lowest terms is 6/13.

Writing a fraction in its simplest form means that the top and bottom numbers can no longer be divided by the same whole number exactly or evenly

The mean of 15 numbers is 12. An extra number is included and the mean increases to 13. What the extra number?

Studentka2010 [4]

Answer: 28

Step-by-step explanation:

The mean of 15 numbers = 12

Then , the sum of the numbers = 12x15 = 180

Let the extra number included be $x$ , then

The new sum = $x + 180$

And the new total number will increase from 15 to 16

new mean = 13 , so we have :

$\frac{x+180}{16} = 13$

$x+ 180 = 16(13)$

$x + 180 = 208$

$x = 208 - 180$

$x = 28$

therefore , the extra number is 28
