Math Problem Statement

What is the sum of 2 3/4 + 3 2/3?

Solution

The image shows the following mixed fractions:

234+3232 \frac{3}{4} + 3 \frac{2}{3}

Step-by-Step Solution:

  1. Convert the mixed fractions to improper fractions:

    • 234=2×4+34=8+34=1142 \frac{3}{4} = \frac{2 \times 4 + 3}{4} = \frac{8 + 3}{4} = \frac{11}{4}
    • 323=3×3+23=9+23=1133 \frac{2}{3} = \frac{3 \times 3 + 2}{3} = \frac{9 + 2}{3} = \frac{11}{3}
  2. Now, add the improper fractions: 114+113\frac{11}{4} + \frac{11}{3} To add fractions, find a common denominator. The least common denominator (LCD) of 4 and 3 is 12.

  3. Rewrite the fractions with the LCD: 114=11×34×3=3312,113=11×43×4=4412\frac{11}{4} = \frac{11 \times 3}{4 \times 3} = \frac{33}{12}, \quad \frac{11}{3} = \frac{11 \times 4}{3 \times 4} = \frac{44}{12}

  4. Now, add the fractions: 3312+4412=33+4412=7712\frac{33}{12} + \frac{44}{12} = \frac{33 + 44}{12} = \frac{77}{12}

  5. Simplify or leave as an improper fraction: 7712\frac{77}{12} This can also be written as a mixed fraction: 7712=6512\frac{77}{12} = 6 \frac{5}{12}

Thus, the sum of 234+323=65122 \frac{3}{4} + 3 \frac{2}{3} = 6 \frac{5}{12}.
