Step-by-step explanation:
Attached is the complete question.
Given: Each student must add 3/8 teaspoon of salt to a solution.
The group only has a 1/8 teaspoon measuring spoon.
Lets assume number of times spoon each students need to fill be "x" to get
for performing experiment.
Now finding the number of times each students need to fill the measuring spoon.
⇒ 
Multiplying both side by 8
⇒ 
∴ x= 3 .
Hence, each students need to fill 3 times teaspoon to perform experiment.
As given there are 4 students in the group, therefore each will add 3 teaspoon to perform experiment.
∴ Total number of times teaspoon to be added = 
Total number of teaspoon to be added= 
∴ 12 number of times teaspoon need to fill the measuring spoon in order to perform experiment.
