Question

job 11 - fractions

note: to find percent of increase or decrease when comparing two numbers, follow these two simple steps:

1. subtract the two numbers
2. divide the answer from step 1 and place it over the original number or the number being compared.

example:
january sales $500
february sales $600

step 1 $600-500 = $100
step 2 \\(\frac{100}{500}\\) = .2 or 20%
in other words, february sales went up 20%.
