With the given ratio of 5:6, let 5x be the number in Inessa's garden and 6x be the number in Ralph's garden.

In the replanting, half of the plants in Inessa's garden are mover to Ralph's garden.

Now we could say the number of plants moved from Inessa's garden to Ralph's garden is 2.5x, or (5/2)x. But if we want to avoid working with fractions or decimals, we can redefine the original numbers in the two gardens as 10x and 12x.

So Ralph started with 12x plants, and 5x plants (half of Inessa's 10x) were moved to his garden.

That gives him 17x plants; and the number in his garden is 850. So 17x = 850; x = 50.

Then the number originally in Ralph's garden is 12x = 600.
