Question

Simplify : (i) 2 $\frac{2}{3}$ . 2 $\frac{1}{5}$ (ii) ($\frac{1}{33}$)7 (iii) 11 $\frac{1}{2}$ / 11$\frac{1}{4}$ (iv) 7 $\frac{1}{2}$ . 8 $\frac{1}{2}$

Answer 1

(i) 2 $\frac{2}{3}$ . 2 $\frac{1}{5}$= 2( $\frac{2}{3}$ + $\frac{1}{5}$)

= 2 $\frac{13}{15}$

(ii) ($\frac{1}{33}$)7 = (3-3)7

= (3)-21

(iii) $\frac{11\frac{1}{2}}{ 11\frac{1}{4}}$

=11$\frac{1}{4}$

(iv) 7 $\frac{1}{2}$ . 8 $\frac{1}{2}$

= (56) $\frac{1}{2}$
