Verified Answer :

5 2/5 - 4 3/4
= 27/5 − 19/4

= ((27 × 4) − (19 × 5)) / (5 × 4) 

= (108 - 95) / 20

= 13/20

= 13/20

Answer:

The tree grew 0.65 feet.

Step-by-step explanation:

We have,

Height of tree when planted = \(4\frac{3}{4}\) = \(\frac{19}{4}\)

Height of tree one year later = \(5\frac{2}{5}\) = \(\frac{27}{5}\)

So, we get that the difference in the height of the tree in a year is,

Difference = \(\frac{27}{5}-\frac{19}{4}\)

i.e. Difference = \(\frac{27\times 4-19\times 5}{20}\)

i.e. Difference = \(\frac{108-95}{20}\)

i.e. Difference = \(\frac{13}{20}\) = 0.65 feet

Hence, the tree grew 0.65 feet.
