Answer 2

Answer: There are 6 sets of markers that will be placed in the storage closet.

Step-by-step explanation:

Since we have given that

Number of sets of markers she orders = 45

Part of sets of markers need to go to the office = $\dfrac{1}{5}$

Part of sets of markers need  to go to art classroom = $\dfrac{2}{3}$

Part of sets of markers will go to the storage closet is given by

$1-(\dfrac{1}{5}+\dfrac{2}{3})\\\\=1-(\dfrac{3+10}{15})\\\\=1-\dfrac{13}{15}\\\\=\dfrac{15-13}{15}\\\\=\dfrac{2}{15}$

So, Number of sets of markers will be placed in the storage closet is given by

$\dfrac{2}{15}\times 45\\\\=2\times 3\\\\=6$

Hence, there are 6 sets of markers that will be placed in the storage closet.
