6.3 m

To find out how high Rajon's plant grows, you need to add the additional height it grows to Allie's plant height.

Given that Rajon's plant grows 3/10 meter higher, you can add this value to Allie's plant height of 6 meters.

To add fractions, you need a common denominator. In this case, the common denominator is 10, so you can rewrite 3/10 as 6/20.

Now you can add the fractions:
6 meters + 6/20 meter

To add the fractions, you need to have the same units. So, you can convert the numerator of the first fraction to have the same denominator as the second fraction:
6 meters + 30/100 meter

Now you can add the two fractions:
6 meters + 30/100 meter = 6 meters + 0.3 meter = 6.3 meters

Therefore, Rajon's plant grows to a height of 6.3 meters.
