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 - 12 pairs
(12 * 3) - 27 = ?
72magnets
there are 24 student in a science class mr sato will give each pair 9f students 3magnets so far mr sato has given 9 pairs of student their 3magnets how many more magnets does mr sato need so that each pair of students has exactly 3magnets
To find out how many more magnets Mr. Sato needs, we first need to determine the total number of pairs of students in the class.
We know that there are 24 students in the class, and for each pair of students, Mr. Sato gives 3 magnets. So, we can divide the total number of students by 2 to find the total number of pairs:
24 students / 2 = 12 pairs of students
Now, we need to subtract the number of pairs that have already received their magnets:
12 pairs of students - 9 pairs who received magnets = 3 pairs of students still needing magnets
Since each pair of students should receive 3 magnets, we can multiply the number of pairs by 3:
3 pairs of students × 3 magnets per pair = 9 magnets
Therefore, Mr. Sato needs 9 more magnets so that every pair of students has exactly 3 magnets.
