Answer:

10 boys

Step-by-step explanation:

if the ratio of boys to girls is 2:1, and 5 girls were there, then 1=5.

since 1=5, we can multiply it by the other number in the ratio: 2.

or you can add 5+5 because there are 2 fives

2x5=10. . therefore, 2=10 so there would be 10 boys.

hope this helps!
There was 10 boys at the movie.

2:1 ratio means there was twice as much boys as girls, 5 x 10 = 10

10 boys is twice as much as 5 girls.
