Find each product or quotient where possible. 1213−43\(\frac{\frac{12}{13}\)}{-\(\frac\)43}

Verified step by step guidance
1
Identify the problem as a division of two fractions: \(\frac{12}{13} \div \left(-\frac{4}{3}\right)\).
Recall that dividing by a fraction is the same as multiplying by its reciprocal. So rewrite the expression as \(\frac{12}{13} \times \left(-\frac{3}{4}\right)\).
Multiply the numerators together and the denominators together: numerator = \(12 \times (-3)\), denominator = \(13 \times 4\).
Write the product as a single fraction: \(\frac{12 \times (-3)}{13 \times 4}\).
Simplify the fraction by reducing common factors if possible, and express the final answer in simplest form.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Dividing Fractions

Dividing fractions involves multiplying the first fraction by the reciprocal of the second. The reciprocal of a fraction is obtained by swapping its numerator and denominator. For example, dividing by 4/3 is the same as multiplying by 3/4.

Simplifying Fractions

Simplifying fractions means reducing them to their lowest terms by dividing numerator and denominator by their greatest common divisor (GCD). This makes the fraction easier to understand and work with, and is often the final step in fraction operations.
