Ryan is building a tree house. he has 18 feet of wood to use. he uses three fourths of a foot of wood to make each step for the ladder. if he has 15 feet of wood left, how many ladder steps did he make?

Ryan made 4 ladder steps of wood left .

Step-by-step explanation:

Total available wood to make ladder  = 18 feet

Total wood left after the ladder is made = 15 ft

So, the wood used to made ladder = Available wood  - Left out Wood

                                                           =  18 ft - 15 ft  = 3 feet

Hence, Ryan used 3 feet of wood to make the ladder steps.

Now, the wood used to make each step = 3/4 foot  = 0.75 ft

Let us assume Ryan makes total n steps.

⇒

or, n = 4

Hence, Ryan made 4 ladder steps of wood left .
