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. How many more magnets does mr sato need so that each pair of students has exactly 3 magnets?

Respuesta :

3 more magnets because in total there will be only 12 pairs since 24 is divided by 2. So 9 times 3 is 27 and 36 magnets- 27 magnets is 3. So he has 3 more to give

24 x 3 = 72 
9 x 3 =27

72-27 =45
Mr. Sato needs to give out 45 more magnets
