How about "miles per hour?" I drive "45 miles per hour" on my way into town.
That's a unit rate.

Did you know that 2 pints = 1 quart? You could write this rate / ratio as

2 pints
---------
1 qt

or as

(1/2 qt)
----------- this is a measure of one quantity per unit of another quantity.

For the direct variation such that when y = 2 then x = 3 , find the constant of variation ( k) and then find the value of y when

Sergeu [11.5K]

Answer:

k is 2/3 and y is -1/3 when x is -0.5.

Step-by-step explanation:

The direct variation relationship is y = kx, where k is the const. of var.

Subbing 3 for x and 2 for y, 2 = 3k, or k = 2/3.

Now, if x = -0.5, y = (2/3)(-1/2) = -1/3

k is 2/3 and y is -1/3 when x is -0.5.

8/15 divided by 1/3 reduce your answer

klio [65]

Here we can use fact than we can multiply fraction by inverse of fraction instead of dividing it.
Inverse of 1/3 is 3/1
Lets multiply it
$\frac{8}{15}* \frac{3}{1}= \frac{24}{15}= \frac{24:3}{15:3}= \frac{8}{5}=1 \frac{3}{5}$ - its our result
