Because of the fact that the amberjack is essentially three snappers, it can be shown as 3s
since one snapper is one s, and the amberjack is 3s, we can combine like terms
s+3s = 4s
because altogether, the fish weigh 44 pounds, 4s would equal 44 (shown as 4s = 44), from there, simply divide by 4 on both sides to get the weight of a snapper;
s = 11
Small bonus (finding an amberjack)
Since an amberjack is equal to three snappers, and a snapper is 11 pounds, an amberjack would be 33 pounds.
To convert a percent to a decimal, you move the the decimal left two places to convert the percent to a decimal. For example, if you were to convert 14% to a decimal, you move the decimal left two places so that 14% converted to a decimal would look something like this: 0.14
1/8 + 3/4 = 1/8 + 6/8 = 7/8 (to the right)
1/8 - 3/4 = 1/8 - 6/8 = -5/8 (to the left)
Answers are 7/8 and -5/8.
