Video Solution

Step-by-Step Solution

To solve the problem of adding 8348\frac{3}{4} and 1151\frac{1}{5}, we can follow these steps:

  • Step 1: Find a common denominator for the fractions 34\frac{3}{4} and 15\frac{1}{5}.

The least common multiple of 4 and 5 is 20. Thus, we need to convert 34\frac{3}{4} and 15\frac{1}{5} to have this common denominator:

34=3×54×5=1520\frac{3}{4} = \frac{3 \times 5}{4 \times 5} = \frac{15}{20}
15=1×45×4=420\frac{1}{5} = \frac{1 \times 4}{5 \times 4} = \frac{4}{20}

  • Step 2: Add the fractional parts using their common denominators.

1520+420=1920\frac{15}{20} + \frac{4}{20} = \frac{19}{20}

  • Step 3: Add the whole numbers.

8+1=98 + 1 = 9

  • Step 4: Combine the results of the fraction and the whole number.

9+19209 + \frac{19}{20}
