Answer:
36
Step-by-step explanation:
Square roots have a neat property: 
provided <em>a</em> and <em>b</em> are positive real numbers.
This property is what's behind simplifying square roots. You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.
Example: 
.
In this problem, both factors are perfect squares.
The easiest to find equivalent fractions is to multiply both the numerator and denominator by the same integer.
For Example, an equivalent fraction for 9/15 is 18/30. I got this answer by multiplying 9*2=18 and 15*2=30.
Another equivalent fraction for 9/15 is 27/45 because 9*3=27 and 15*3=45.
******Note
Just make sure that you always multiply the numerator and denominator by the same number, or else your fractions won't be equivalent!!
Ok, so there were 30 students at the field trip with Ms. Bird, 24 students at the field trip with Mr. Torres, and 36 students with Mrs. Allen at the field trip. What is your question?
