At lunch, $60\%$ of the students selected soda while $20\%$ selected milk. if 72 students selected soda, how many students selected milk?

24 students selected milk

Step-by-step explanation:

Let x be the total number of students,

Since, 60% of students selected soda,

⇒ Number of students who selected soda = 60% of x = 0.6x

According to the question,

0.6x = 72

Divide both sides by 0.6,

⇒ x = 120

Now, 20% students selected milk

Hence, the number of student who selected milk = 20% of 120 = 0.20 × 120 = 24

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
