Answer 1

1:2:6

Step-by-step explanation:

just took the test :D

Answer 2

The ratio of beryllium to aluminum to sillicate is 1:2:6

Step-by-step explanation:

1. First write down the compound:

`BeAl_(2)(SiO_(3))_(6)`

2. Then to know the ratio between them, write them down separately:

Beryllium: Be

Aluminum: Al

Silicate:
`SiO_(3)`

3. Write the quantity of each of them in the compound, that is the subscript:

Beryllium: Be = 1

Aluminum: Al = 2

Silicate:
`SiO_(3)` = 6

4. Therefore the ratio of beryllium to aluminum to sillicate is 1:2:6
