One fifth of the plants in a vegetable garden are cucumber plants. If there are 8 cucumber plants what equation can be used to find the total number of plants in the garden?

let the total number of plants = x
one fifth of x = x/5
so number of cucumber plants = x/5
but it is given that there are 8 cucumber plants.

so "x/5 = 8"
it is the required equation to find the number of plants in garden.(x is number of plants in the garden)
