173.76÷54.3

​

Answer 1

$20.5380 \div 6.3 \\ \\ = \frac{205380}{10000} \div \frac{63}{10} \\ \\ \\ = \frac{ \frac{205380}{10000} }{ \frac{63}{10} } \\ \\ = \frac{205380 \times 10}{10000 \times 63} \\ \\ = \frac{205380}{63000} \\ \\ = \frac{163}{50} \\ \\ = 3.26$

$178.5875 \div 70.31 \\ \\ = \frac{1785875}{10000} \div \frac{7031}{100} \\ \\ \\ = \frac{ \frac{1785875}{10000} }{ \frac{7031}{100} } \\ \\ = \frac{1785875 \times 100}{10000 \times 7031} \\ \\ = \frac{1785875}{703100} \\ \\ = 2.540001$

$173.76 \: \div 54.3 \\ \\ = \frac{17376}{100} \div \frac{543}{10} \\ \\ \\ = \frac{ \frac{17376}{100} }{ \frac{543}{10} } \\ \\ = \frac{17376 \times 10}{100 \times 543} \\ \\ = \frac{17376}{5430} \\ \\ = \frac{16}{5} \\ \\ = 3.2$
