Q. At Norma's Vacation Wear, 310\frac{3}{10} of the garments are bikinis and 25\frac{2}{5} are trunks. What fraction of the garments are either bikinis or trunks?\newlineWrite your answer as a fraction or as a whole or mixed number.\newline_____  of the garments
  1. Identify fractions: Step 11: Identify the fractions to be added.\newlineWe have 310\frac{3}{10} of the garments as bikinis and 25\frac{2}{5} as trunks. We need to add these fractions to find the total fraction of garments that are either bikinis or trunks.\newline310+25\frac{3}{10} + \frac{2}{5}
  2. Find common denominator: Step 22: Find a common denominator.\newlineThe denominators are 1010 and 55. The least common denominator (LCD) is 1010.\newline25\frac{2}{5} can be converted to 410\frac{4}{10} to have the same denominator.\newline310+410\frac{3}{10} + \frac{4}{10}
  3. Add fractions: Step 33: Add the fractions.\newlineNow that both fractions have the same denominator, add the numerators.\newline310+410=710\frac{3}{10} + \frac{4}{10} = \frac{7}{10}
