Math Problem Statement

Evaluate the expression: (1/16) / (1/12) + 12/11.

Solution

To solve the given expression, we need to evaluate it step by step. The expression is:

116112+1211\frac{\frac{1}{16}}{\frac{1}{12}} + \frac{12}{11}

Step 1: Simplify the division of fractions

Simplify 116112\frac{\frac{1}{16}}{\frac{1}{12}}.

This can be rewritten as:

116÷112=116×121=1216\frac{1}{16} \div \frac{1}{12} = \frac{1}{16} \times \frac{12}{1} = \frac{12}{16}

Simplify 1216\frac{12}{16} by dividing both the numerator and denominator by 4:

1216=34\frac{12}{16} = \frac{3}{4}

Step 2: Add 34\frac{3}{4} and 1211\frac{12}{11}

To add these fractions, find a common denominator. The least common denominator (LCD) of 4 and 11 is 44.

Convert 34\frac{3}{4} and 1211\frac{12}{11} to have the same denominator:

34=3×114×11=3344\frac{3}{4} = \frac{3 \times 11}{4 \times 11} = \frac{33}{44}

1211=12×411×4=4844\frac{12}{11} = \frac{12 \times 4}{11 \times 4} = \frac{48}{44}

Now add the fractions:

3344+4844=33+4844=8144\frac{33}{44} + \frac{48}{44} = \frac{33 + 48}{44} = \frac{81}{44}

Final Answer

8144\frac{81}{44}
