Brooke gave her dog two whole biscuits and a half of a biscuit. write a mixed number the represents the amount of dog biscuits she gave her dog.

Your 2 1/2 (The integer two, and the proper fraction one all over two.)

Explanation: If Brooke gave her dog two whole biscuits and then a half, it would sum up to the improper fraction 5/2 (Five all over two.) When you divide 5 by 2, you get 2.5, which is equivalent to 2 1/2.

Hope this helps ya :D

step-by-step explanation:

f

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
