Question

Mrs.Wright says that two-thirds of her class has arrived for the day. If 10 students have arrived, how many students are in her class?

Answer 1

Let's set up an algebraic equation.
We can use the keyword "of" to mean multiplication.
Therefore, we have:
2/3x = 10
We multiply both sides by 3 to clear the denominator. We get:
2x=30
Divide both sides by 2 to get
x = 15.
15 students are in Mrs. Wright's class.
Hopefully this helped!
