Answer:
12 times.
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 [tex]\frac{3}{8} \ teaspoon[/tex] for performing experiment.
Now finding the number of times each students need to fill the measuring spoon.
⇒ [tex]\frac{1}{8} \times x= \frac{3}{8}[/tex]
Multiplying both side by 8
⇒ [tex]x= \frac{3\times 8}{8}= 3[/tex]
∴ 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 = [tex]number\ of\ spoon\ by\ each\ student\times total\ number\ of\ students[/tex]
Total number of teaspoon to be added= [tex]3\times 4= 12[/tex]
∴ 12 number of times teaspoon need to fill the measuring spoon in order to perform experiment.
