Answer:
12
Step-by-step explanation:
We can write the following ratio
1:3 (for every student who gets an A 3 gets a b)
We then can write a new ratio
4:x
We can solve this ratio by multiplying the original ratio by 4
4:12
This means that 12 people earned an B
We can break √10 into √2 • √5, and √8 into √2 • √4, or, simplifying √4 to 2, 2 • √2. Our expression now becomes
(√2 • √5) / (4 • 2 • √2)
Cancelling the √2 in the numerator and denominator gets us
√5/(4 • 2), or √5/8.
