The number of shelves stephen can make is approximately 27
Solution:
Given that Stephen makes wooden shelves for his room
Stephen wants to make the shelves 3/4 foot long
He starts with a board that is 20 feet long
To find: number of shelves he can make
So the number of shelves stephen can make can make is found out by dividing 20 feet long board by 3/4 foot long
![\text {number of shelves }=\frac{\text { total length of board stephen has }}{\text { length of each board }}](https://img.qammunity.org/2020/formulas/mathematics/high-school/k4x9z6b0x90m6vlitvmwafq365kwl5gyi4.png)
![\text {number of shelves }=(20)/(3 / 4)=(20)/(0.75)=26.6](https://img.qammunity.org/2020/formulas/mathematics/high-school/wfb24jtgb431a0tvojzc4vgp85rmdaylnf.png)
So the number of shelves stephen can make is approximately 27
