Atree grow 1/4 foot in 1/12 year.

part a: write the rate at which this tree grows as a fractions.

part b: how many feet does the tree grow in 1 year? explain how you know.

Part A) The rate is

Part B) In 1 year the tree grows 3 feet

Step-by-step explanation:

Part A)  write the rate at which this tree grows as a fractions

we know that

To find out the rate at which the tree grows divide 1/4 foot by 1/12 year

so

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of

Simplify

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet

i think that you should ask google for the answer to that problem because if we don't know it google does
