A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?

The tree grew 15/64 meters per year.                  

Step-by-step explanation:

Given

To determine

Per year growth of the tree in meters

Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.

Per year growth of tree = Total Length  / Total time to grow

                                       = 3/4 ÷ 16/5

                                        = 3/4 × 5/16

                                        = [3×5] / [4×16]

                                        = 15/64 meters

Therefore, the tree grew 15/64 meters per year.                  

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
