Step-by-step explanation:
The answer is B.) one of the numbers is negative.
So if you take the example...
-3 x -7 = 21
then we know that they equal a positive.
21 ÷ -3 = -7
add 0+1+2+3+4 = 10
divide 10÷5 = 2
add 15+8+3+3+1 = 30
divide 30÷5 = 6
the ratio is 2:6 which simplifies to 1:3 by the means of lates per student. In other words there is one late per 3 students.
