Question

Devide the sum of 13/5 and  4/15 by their difference.   ​

Answer 1

$sum = \frac{13}{5} + \frac{4}{15} \\ \frac{39 + 4}{15} \\ = \frac{43}{15} \\ difference = \frac{39 - 4}{15} \\ = \frac{35}{15} \\ = \frac{7}{3} \\ dividing \: sum \: and \: difference \\ = \frac{43}{15} \div \frac{7}{3} \\ = \frac{43}{15} \times \frac{3}{7} \\ = \frac{43}{21}$
