The ratio of red apples to green apples on a farm is 3:1. If there are 180 red apples on the farm, how many green apples are there?

There is 60 green apples

Step-by-step explanation:

Since there is 1 green apple for every three red apples you could divide 180 by 3 which would equal 60 so there is 60 green apples.

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.

the answer for this question is 38
