there are 24 students in a science class. Mr. Sato will give each pair of students 3 magnets. So far, Mr. Sato has given 9 pairs of students their 3 magnets. homw many more magents does Mr. Sato need so that each pair of students has excatly 3 magnets.
24/2*3-9*3
You guys are weird it is 34567.5467
Since they are given to pairs of students, you need 12*3 = 36 magnets in all. He has already given 9*3 = 27 magnets. What does that tell you?
I have no idea

To find out how many more magnets Mr. Sato needs, we first need to determine the total number of magnets that have been distributed so far. We can do this by multiplying the number of pairs of students by the number of magnets given to each pair.
Given that Mr. Sato has given 9 pairs of students their 3 magnets, we can calculate the total number of magnets distributed as follows:
Total number of magnets distributed = Number of pairs of students × Magnets given to each pair
= 9 pairs × 3 magnets
= 27 magnets
Since there are 24 students in the class, there are 12 pairs of students (24 students ÷ 2) in total. Each pair should have exactly 3 magnets. Therefore, the ideal number of magnets needed to distribute equally among all pairs is:
Ideal total number of magnets = Number of pairs of students × Magnets given to each pair
= 12 pairs × 3 magnets
= 36 magnets
To find out how many more magnets Mr. Sato needs, we subtract the total number of magnets distributed from the ideal total number of magnets:
Number of more magnets needed = Ideal total number of magnets - Total number of magnets distributed
= 36 magnets - 27 magnets
= 9 magnets
Therefore, Mr. Sato needs 9 more magnets in order for each pair of students to have exactly 3 magnets.
