Question:

Answer 1

Chemical formula \[(SiO_2)_{0.63}(Al_2O_3)_{0.21}(FeO)_{0.37}(MgO)_{0.16}(MnO)_{0.11}\]

How do I simply convert these to whole numbers so it's nice and neat?

Answer 2

I've tried diving by the lowest number and using the LCD but both got me nowhere fast

Answer 3

Answer 6

The best I can come up with is
\[ (SiO_2)_{3}(Al_2O_3)\ [(FeO)_{7}(MgO)_{3}(MnO)_{2}]_\frac{1}{4} \]
