Video Solution

Solution Steps

00:07 Let's solve this problem together.
00:10 First, we need the least common denominator.
00:14 We'll multiply by three, and then by two, to get a common denominator of 18.
00:20 Make sure to multiply both the top and bottom of the fraction.
00:30 Great! Now, let's do the multiplication.
00:37 Add everything together under the common denominator.
00:44 Next, add up the numerators.
00:50 And that's how we find the solution!

Step-by-Step Solution

To solve the addition of fractions 26+39 \frac{2}{6} + \frac{3}{9} , we will follow these logical steps:

  • Step 1: Find a common denominator.
    The denominators are 66 and 99. The least common multiple (LCM) of these numbers is 1818.
  • Step 2: Convert each fraction to have the denominator of 1818.
    To convert 26\frac{2}{6} to a denominator of 1818, multiply both the numerator and the denominator by 33 (because 6×3=186 \times 3 = 18): 26=2×36×3=618 \frac{2}{6} = \frac{2 \times 3}{6 \times 3} = \frac{6}{18} To convert 39\frac{3}{9} to a denominator of 1818, multiply both the numerator and the denominator by 22 (because 9×2=189 \times 2 = 18): 39=3×29×2=618 \frac{3}{9} = \frac{3 \times 2}{9 \times 2} = \frac{6}{18}
  • Step 3: Add the fractions.
    Now that both fractions have the same denominator, add their numerators: 618+618=6+618=1218 \frac{6}{18} + \frac{6}{18} = \frac{6 + 6}{18} = \frac{12}{18}
  • Step 4: Simplify if possible.
    Check if 1218\frac{12}{18} can be simplified. The greatest common divisor (GCD) of 1212 and 1818 is 66, so: 1218=12÷618÷6=23 \frac{12}{18} = \frac{12 \div 6}{18 \div 6} = \frac{2}{3} However, since the original question focused on achieving the fraction with denominator 1818, our final non-simplified answer remains 1218\frac{12}{18}.

The final result is that the sum of the fractions is 1218\frac{12}{18}.

Answer

1218 \frac{12}{18}
