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 \(\frac{1}{2}\)
(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) \(\frac{1}{2}\)
Find: (i) 9 \(\frac{3}{2}\) (ii) 32 \(\frac{2}{5}\) (iii) 16 \(\frac{3}{4}\) (iv) 125 -\(\frac{1}{3}\)
