Question: Carla is making smoothies. If she uses 500 ml of watermelon puree and 100 ml of cream, how many 150 ml servings can she make?
Answer with step-by-step thinking: First find the total volume of the smoothie mix: 500 ml + 100 ml = 600 ml. Then divide the total volume by the volume per serving to find the number of servings: 600 ml / 150 ml / serving = 4 servings.

Question: Annie has 6 barrettes, twice as many scrunchies as barrettes, and three fewer bobby pins than barrettes. What percentage of her hair decorations are bobby pins, rounded to the nearest percent?
Answer with step-by-step thinking: First find the total number of scrunchies: 6 barrettes * 2 = 12 scrunchies. Then subtract three fewer bobby pins than barrettes 6 - 3 = 3 bobby pins. Then add the number of each type of hair decorations to find the total number: 6 decorations + 12 decorations + 3 decorations = 21 decorations. Then divide the number of bobby pins by the total number of decorations and multiply by 100% to express the answer as a percentage: 3 bobby pins / 21 decorations * 100% = 14.28 which rounds down to 14%.
So the answer is 14.
