1. Problem Description

The problem is to evaluate the expression 34+14×23\frac{3}{4} + \frac{1}{4} \times \frac{2}{3}.

2. Solution Steps

To solve this problem, we need to follow the order of operations (PEMDAS/BODMAS), which states that multiplication should be performed before addition.
First, we multiply the two fractions 14\frac{1}{4} and 23\frac{2}{3}:
14×23=1×24×3=212\frac{1}{4} \times \frac{2}{3} = \frac{1 \times 2}{4 \times 3} = \frac{2}{12}
We can simplify the fraction 212\frac{2}{12} by dividing both the numerator and the denominator by their greatest common divisor, which is 2:
212=2÷212÷2=16\frac{2}{12} = \frac{2 \div 2}{12 \div 2} = \frac{1}{6}
Now we add the result to the first fraction:
34+16\frac{3}{4} + \frac{1}{6}
To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 4 and 6 is
1

2. We convert both fractions to have a denominator of 12:

34=3×34×3=912\frac{3}{4} = \frac{3 \times 3}{4 \times 3} = \frac{9}{12}
16=1×26×2=212\frac{1}{6} = \frac{1 \times 2}{6 \times 2} = \frac{2}{12}
Now we can add the fractions:
912+212=9+212=1112\frac{9}{12} + \frac{2}{12} = \frac{9 + 2}{12} = \frac{11}{12}

3. Final Answer

1112\frac{11}{12}
