working out equivelent fractions is simple you take a fraction-in you case 1/2 and do the same to each number in the fraction. You can multiply or divide but you can't add or subtract for example you can double both 1 and 2 and get 2/4 you could times both by 1000 and get 1000/2000 All of these are equivelent fractions
First you would have to find the greatest common factor of 58 and 1000. Then you would divide that into both 58 and 1000 to get your answer. Since the GCF of both te numbers is 2, then you divide both numbers by 2. The answer would be 29 out of 500. GCf: GCF stands for greatest common factor. The greatest common factor of two numbers is the largest number that can go into both of them. You need to use the GCF to put numbers in their simplest form.
1000000, 100^3=1000000, and 1000^2=1000000

The element symbol for argon, Ar, is derived from the first two letters of the element's name.
Two - D & G are both worth 2pts a piece.
The symbol for an element is typically derived from its name. In the case of bromine, the symbol "Br" comes from the element's Latin name "bromum".
Ca+2 -Don't forget capital and lowercase letters, as well as the correct charge (remember-the +2 or 2+ , is written in small (letters), on the top right side of the end letter) . I've been learning this very recently in class I hope it helps you :)
The atomic symbol for aluminum, "Al," comes from its name in Latin, "alumen." This Latin word was used to refer to alum, a compound that contains aluminum. The symbol "Al" was later chosen to represent aluminum in the periodic table.

(Fe) Iron is from the Latin name ferrous. Two letters to probably differentiate from fluorine. Not I for iron because we have iodine maybe.
