Answer:
The ratio of beryllium to aluminum to sillicate is 1:2:6
Explanation:
1. First write down the compound:
[tex]BeAl_{2}(SiO_{3})_{6}[/tex]
2. Then to know the ratio between them, write them down separately:
Beryllium: Be
Aluminum: Al
Silicate: [tex]SiO_{3}[/tex]
3. Write the quantity of each of them in the compound, that is the subscript:
Beryllium: Be = 1
Aluminum: Al = 2
Silicate: [tex]SiO_{3}[/tex] = 6
4. Therefore the ratio of beryllium to aluminum to sillicate is 1:2:6
