Here the answer is 19/35
Step-by-step explanation:
[tex]\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}[/tex]
We will apply BODMAS rule
In this rule multiplication comes before add and subtraction
= [tex]\frac{-6}{35} + \frac{4}{5} - \frac{3}{35}[/tex]
= [tex]\frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})[/tex]
= [tex]\frac{4}{5} - \frac{9}{35}[/tex]
= [tex]\frac{4 X 7}{5 X 7} -\frac{9}{35}[/tex]
= [tex]\frac{28}{35} - \frac{9}{35}[/tex]
= [tex]\frac{19}{35}[/tex]
