Question

Find the multiplicative inverse (i.e., reciprocal) of :

(i) $\frac{13}{25}$ (ii) $\frac{-17}{12}$ (iii) $\frac{-7}{24}$ (iv) $18$ (v) $-16$

(vi) $\frac{-3}{-5}$ (vii) $-1$ (viii) $\frac{0}{2}$ (ix) $\frac{2}{-5}$ (x) $\frac{-1}{8}$

Answer 1

(i) Multiplicative inverse of $\frac{13}{25}=\frac{25}{13}$

(ii) Multiplicative inverse of $\frac{-17}{12}=\frac{-12}{17}$

(iii) Multiplicative inverse of $\frac{-7}{24}=\frac{24}{-7}$

(iv) Multiplicative inverse of $18=\frac{1}{18}$

(v) Multiplicative inverse of $-16=\frac{-1}{16}$

(vi) Multiplicative inverse of $\frac{-3}{-5}=\frac{-5}{-3}$

(vii) Multiplicative inverse of -1 = -1

(viii) Multiplicative inverse of $\frac{0}{2}=$ does not exists.

(ix) Multiplicative inverse of $\frac{2}{-5}=\frac{-5}{2}$

(x) Multiplicative inverse of $\frac{-1}{8}=-8$
