Video Solution

Step-by-Step Solution

To solve 912+2139\frac{1}{2} + 2\frac{1}{3}, we will perform the following steps:

  • Convert each mixed number to an improper fraction.
  • Find a common denominator for these fractions.
  • Add the fractions together.
  • Convert the result back to a mixed number, if necessary.

Let's start by converting the mixed numbers:

9129\frac{1}{2} becomes 192 \frac{19}{2} because 9×2+1=199 \times 2 + 1 = 19.

2132\frac{1}{3} becomes 73 \frac{7}{3} because 2×3+1=72 \times 3 + 1 = 7.

Next, we find a common denominator for 192 \frac{19}{2} and 73 \frac{7}{3} . The common denominator of 2 and 3 is 6.

Convert 192 \frac{19}{2} to an equivalent fraction with a denominator of 6:

192=19×36=576 \frac{19}{2} = \frac{19 \times 3}{6} = \frac{57}{6} .

Convert 73 \frac{7}{3} to an equivalent fraction with a denominator of 6:

73=7×26=146 \frac{7}{3} = \frac{7 \times 2}{6} = \frac{14}{6} .

Add the fractions:

576+146=57+146=716 \frac{57}{6} + \frac{14}{6} = \frac{57 + 14}{6} = \frac{71}{6} .

Convert 716\frac{71}{6} back to a mixed number:

71÷6=1171 \div 6 = 11 with a remainder 55.

Therefore, 716=1156\frac{71}{6} = 11\frac{5}{6}.

Thus, the result of adding 912+2139\frac{1}{2} + 2\frac{1}{3} is 1156 \mathbf{11\frac{5}{6}} .

Answer

1156 11\frac{5}{6}
