Question

Bryan is sitting on a bench in the mall. He noticed that 18 out of the last 60 men who walked by had a beard. Considering this data, how many of the next 90 men who walk by should Bryan expect to have a beard?

Answer 1

Answer:

27

Step-by-step explanation:

every 30 men = 9 men with beards

you have 30 3 times in 90 so you get 27

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

3×9=27

Answer 2

Answer:

27 is correct

Step-by-step explanation:

18 out of the last 60 men who walked by had a beard.

based on the given condition formulate

$\boxed{\frac{18}{60}=\frac{x}{90} }$

$\boxed{60x=18(90)}$

$\boxed{\frac{18~x~90}{60} }$

$\boxed{x=27}$

Another way to solve↓

60÷2=30

18÷2=9

30 men normal = 9 men with beards

90÷30=3

how many of the next 90 men who walk by

you have 30 × 3  = 90 so you get 27

3 × 9 = 27

Therefore the correct answer is 27
