Solution Steps

Divide \frac{\frac{11}{15}}{-\frac{2\times 5+3}{5}} by \frac{9}{13} by multiplying \frac{\frac{11}{15}}{-\frac{2\times 5+3}{5}} by the reciprocal of \frac{9}{13}.

$$|\frac{\frac{11}{15}\times 13}{\left(-\frac{2\times 5+3}{5}\right)\times 9}|$$

Express \frac{11}{15}\times 13 as a single fraction.

$$|\frac{\frac{11\times 13}{15}}{\left(-\frac{2\times 5+3}{5}\right)\times 9}|$$

Multiply 11 and 13 to get 143.

$$|\frac{\frac{143}{15}}{\left(-\frac{2\times 5+3}{5}\right)\times 9}|$$

Multiply 2 and 5 to get 10.

$$|\frac{\frac{143}{15}}{\left(-\frac{10+3}{5}\right)\times 9}|$$

Add 10 and 3 to get 13.

$$|\frac{\frac{143}{15}}{-\frac{13}{5}\times 9}|$$

Express -\frac{13}{5}\times 9 as a single fraction.

$$|\frac{\frac{143}{15}}{\frac{-13\times 9}{5}}|$$

Multiply -13 and 9 to get -117.

$$|\frac{\frac{143}{15}}{\frac{-117}{5}}|$$

Fraction \frac{-117}{5} can be rewritten as -\frac{117}{5} by extracting the negative sign.

$$|\frac{\frac{143}{15}}{-\frac{117}{5}}|$$

Divide \frac{143}{15} by -\frac{117}{5} by multiplying \frac{143}{15} by the reciprocal of -\frac{117}{5}.

$$|\frac{143}{15}\left(-\frac{5}{117}\right)|$$

Multiply \frac{143}{15} times -\frac{5}{117} by multiplying numerator times numerator and denominator times denominator.

$$|\frac{143\left(-5\right)}{15\times 117}|$$

Do the multiplications in the fraction \frac{143\left(-5\right)}{15\times 117}.

$$|\frac{-715}{1755}|$$

Reduce the fraction \frac{-715}{1755} to lowest terms by extracting and canceling out 65.

$$|-\frac{11}{27}|$$

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of -\frac{11}{27} is \frac{11}{27}.
