Can you explain the multicaion?

Answer 1

1/10

Explanation:

The fraction 5/10 is equal to 1/2 and 1/5 of the girls wears glasses so if you multiply 1/2 and 1/5 you get 1/10.

`(1)/(5)`·
`(1)/(2)`=
`(1)/(10)`

When multiplying fractions you multiply across so the numerators are multiplied together and the denominators are multiplied together.
