Question

3 1/3÷5/3-1/10×21/2+7/4 solution ​

Answer 1

$3\frac{1}{3} \div \frac{5}{3} - \frac{1}{10} \times \frac{21}{2} + \frac{7}{4}$

$\frac{10}{3} \times \frac{3}{5} - \frac{1}{10} \times \frac{21}{2} + \frac{7}{4}$

$2 - \frac{21}{20} + \frac{7}{4}$

$\frac{40 - 21 + 35}{20} \\ (after \: take \: lcm \: of \: 1 \: \: 20 \: \: and \: 4)$

$\frac{54}{20} = \frac{27}{10} \: \: ans.$
