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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
