There are 12 third grade students and 15 fourth grade students in the band. they will travel to a convert in cars that can hold 4 students each. which of these can be used to find out how many cars are needed to drive the students? (12 + 15) ÷ 4 = s (15 - 12) ÷ 4 = s 15 + 12 - 4 = s 15 + 12 + 4 = s

(12+`15) ÷ 4 = s

that is because you have to basically do average for this problem

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

180 square centimeters
