1. Problem Description

The problem is to evaluate the expression (38×916)÷14(\frac{3}{8} \times \frac{9}{16}) \div \frac{1}{4}.

2. Solution Steps

First, we perform the multiplication inside the parenthesis.
38×916=3×98×16=27128\frac{3}{8} \times \frac{9}{16} = \frac{3 \times 9}{8 \times 16} = \frac{27}{128}
Next, we divide the result by 14\frac{1}{4}. Dividing by a fraction is the same as multiplying by its reciprocal.
The reciprocal of 14\frac{1}{4} is 41\frac{4}{1}, which is equal to
4.
27128÷14=27128×4=27×4128=108128\frac{27}{128} \div \frac{1}{4} = \frac{27}{128} \times 4 = \frac{27 \times 4}{128} = \frac{108}{128}
Finally, we simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is
4.
108128=108÷4128÷4=2732\frac{108}{128} = \frac{108 \div 4}{128 \div 4} = \frac{27}{32}

3. Final Answer

The final answer is 2732\frac{27}{32}.
