There are 29 students in a classroom with 7 tables. If 4 students can sit at a table, how
many students cannot sit down at tables?

one student cannot sit down at tables

Step-by-step explanation:

There are 29 students and 7 tables 4 students can sit at each table.  7 x 4 = 28

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
