Kareem wrote the expressions shown. lceil 3 point 2 rceil lfloor 2 point 7 rfloor lceil 2 point 9 rceil lfloor 4 point 8 rfloor Which pair is equivalent?

The ceiling gives the least integer greater than or equal to a number, so ⌈3.2⌉ = 4. The floor gives the greatest integer less than or equal to a number, so ⌊4.8⌋ = 4. These expressions are equivalent, so the correct choice is “⌊4.8⌋ and ⌈3.2⌉.”
