Question

1/3+4/5+2/5-4/7
please solution​

Answer 1

$\huge \bold \red{\frac{1}{3} + \frac{4}{5} + \frac{2}{5} - \frac{4}{7} }$

$\huge \bold \red{LCM = 105}$

$\huge \bold \red{\frac{1}{3} \times \frac{35}{35} = \frac{35}{105} }$

$\huge \bold \red{ \frac{4}{5} \times \frac{21}{21} = \frac{84}{105} }$

$\huge\bold \red{ \frac{2}{5} \times \frac{21}{21} = \frac{42}{105} }$

$\huge \bold \red{ \frac{4}{7} \times \frac{15}{15} = \frac{60}{105} }$

$\huge\bold \red{ \frac{35}{105} + \frac{84}{105} + \frac{42}{105} - \frac{60}{105} }$

$\huge \bold \red {\frac{101}{105} }$
