Answer 2

♡Answer♡:-

$q.2 \\( i). \frac{13}{3125} \\ = \frac{13 \times {2}^{5} }{ {5}^{5} \times {2}^{5} } \\ = \frac{416}{ {10}^{5} } \\ = 0.00416(ans)$

$(ii) \frac{17}{8} \\ = \frac{17 \times {5}^{3} }{ {2}^{3} \times {5}^{3} } \\ = \frac{17 \times 125}{ \ {10}^{3} } \\ = \frac{2125}{1000} \\ = 2.125(ans)$

$(iv) \frac{15}{1600} \\ = \frac{15}{ {2}^{6} \times {2}^{5} } \\ = \frac{15 \times {5}^{4} }{ {2}^{6} \times {5}^{2} \times {5}^{4} } \\ = \frac{15 \times 625}{ {10}^{6} } \\ = \frac{9375}{ {10}^{6} } \\ = 0.009375(ans)$

$(vi) \frac{23}{ {2}^{3} \times {5}^{2} } \\ = \frac{23 \times 5}{ {2}^{3} \times {5}^{2} \times 5 } \\ = \frac{115}{ {10}^{3} } \\ = 0.115(ans)$

$(ix) \frac{35}{50} \\ = \frac{35}{ {5}^{2} \times 2} \\ = \frac{35 \times2 }{ {5}^{2} \times 2 \times 2 } \\ = \frac{70}{ {10}^{2} } \\ = 0.7(ans)$

It may help....
