Answer:To find out how many candies Lino and Lina have in total, we need to add their individual amounts together.Lino's candies: \( \frac{45}{12} \) g Simplify: \( \frac{45}{12} = \frac{15}{4} \) g Lina's candies: \( \frac{51}{3} \) g Simplify: \( \frac{51}{3} = 17 \) g Now, add them together: \( \frac{15}{4} + 17 = \frac{15}{4} + \frac{68}{4} = \frac{83}{4} \) g Convert \( \frac{83}{4} \) to a decimal: \( \frac{83}{4} = 20.75 \) g So, the siblings have 20.75 grams of candies in total.
