Which story problem goes to this division problem 1/2 divided by 2/5 A. a piece of wrapping paper is 1/2 yard wide and 2/5 yard long what is the area of wrapping paper?
b. the area of a wetland is 2/5 square mile and it is 1/2 mile length how wide is the wetland?
c. a whiteboard is 2/5 meter long and has an area of 1/2 square meter how wide is the whiteboard?
d. a mosaic has an area of 2/5 square foot and a width of 1/2 foot what is the length of the mosaic? i need a answer quick please

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.

answer: 4 (:
