Ratios or Percentages?

Sky decides that she wants to buy something from the store today. She spends some of her money on beads for jewelry, and some of her money on blankets. She wonders how much of her money she has spent on her blanket. Sky, in this case, has the option of using either ratios or percentages to figure out how much money was used. Lets just say she spends a total of 100$ and, 40$ on the blanket its self. You can pu that into t fraction, (40/100), which should be equivalent to 40%. Now she can figure out that the other 60% was used on the beads on the jewelry. Ratios, and percentages are all related in some way. If you put both into a fraction, they can equal to eachother. Fraction, percentages, and ratios are all equal. Now, me myslef, I would rather prefer to use the percentages over the ratios, simply because in buying items, or even tax is calculated using percentages.
     Say she spent a bit more money over all.
