Question

7. For the summer camp, Josie orders 45
sets of markers. One-fifth of the sets of
markers need to go to the office, of the
sets go to the art classroom, and the
remainder will go to the storage closet. How
many sets of markers will be placed in the
storage closet?
what’s the answer?

Answer 1

Answer: 27 markers

Step-by-step explanation: 1/5 of 45 is 9 and 9 times 2 is 18. 45 minus 18 is 27. Boom.

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.
