18 students decide they don't want to be rescued and want to continue to live in the jungle . If this represents 40% of the student, How many students want to be rescued?

let y be the total number of students.

y×40/100=18

18×100/40=y

45=y

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

good luck on your studies! : )
