Question

1. Find the multiplicative inverse or reciprocal of each of the following:
(i) 18
(ii) -16
(iii) \(\frac {13}{25}\)
(iv) \(\frac {-17}{12}\)
(v) \(\frac {-6}{19}\)
(vi) \(\frac {-3}{-5}\)
(vii) -1
(viii) 0
2. Simplify:
(i) \(\frac {4}{9}\div (\frac {-5}{12})\)
(ii) \(-8\div (\frac {-5}{16})\)
(iii) \(\frac{−12}{7}\div (−18)\)
(iv) \((\frac {-1}{10})\div (\frac {-8}{5})\)
(v) \((\frac{−16}{35})\div (\frac{−15}{14})\)
(vi)\((\frac {-65}{14})\div (\frac {13}{-7})\)

Answer

Answer for 1. Find the multiplicative inverse or reciprocal of each of the following: (i) 18 (ii) -16 (iii) frac {13}{25} (iv) frac {-17}{12} (v) frac {-6}{19} (vi) frac {-3}{-5} (vii) -1 (viii) 0 2.
