1. Problem Description

We need to evaluate the expression 34+14×23\frac{3}{4} + \frac{1}{4} \times \frac{2}{3}.

2. Solution Steps

Following the order of operations, we first multiply the fractions 14\frac{1}{4} and 23\frac{2}{3}.
Multiplication of fractions:
ab×cd=a×cb×d\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}
So, 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 212\frac{2}{12} to 16\frac{1}{6} by dividing both the numerator and the denominator by
2.
Now we have 34+16\frac{3}{4} + \frac{1}{6}.
To add the fractions, we need a common denominator. The least common multiple of 4 and 6 is
1

2. We convert $\frac{3}{4}$ to a fraction with a denominator of 12:

34=3×34×3=912\frac{3}{4} = \frac{3 \times 3}{4 \times 3} = \frac{9}{12}.
We convert 16\frac{1}{6} to a fraction with a denominator of 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}
