Question

(-2/5) - (-5/7)
Solve the above question with full formula.​

Answer 1

Answer:

$( \frac{ - 2}{5} ) - ( \frac{ - 5}{7} ) \\ \\ = \frac{ -2 }{5} + \frac{5}{7} \\ \\ = lcm = 57 \times 7 = 35 \\ \\ \frac{ - 2}{5} \times \frac{7}{7} = \frac{ - 14}{35} \\ \\ \frac{5}{7} \times \frac{5}{5} = \frac{25}{35} \\ \\ = \frac{25 - 14}{35} \\ \\ = \frac{ 11}{35}$

Answer 2

Step-by-step explanation:

(-2/5) - (-5/7)

_________________________

$\boxed{ \huge{ \bold{Given}}}$

• $\large{ \sf{ ( \frac{ - 2}{5} ) - (\frac{ - 5}{7} )}}$

$\boxed{ \huge{ \bold{to \: find}}}$

• Value of the Following Number

$\star{ \pink{ \large{ \sf{ \underline{ \underline{Solution : - }}}}}}$

$\large{ \sf{ ( \frac{ - 2}{5} ) - (\frac{ - 5}{7} )}}$

${ \red \rightarrow{\large{ \sf{ ( \frac{ - 2}{5} ) + (\frac{ 5}{7} )}}}}$

${ \red \rightarrow{\large{ \sf{ \frac{ - 2}{5} + \frac{ 5}{7} }}}}$

${ \red \rightarrow{\large{ \sf{ \frac{ - 2 \times 7}{5 \times 7} + \frac{5 \times 5}{7 \times 5}}}}}$

${ \red \rightarrow{\large{ \sf{ \frac{ - 14}{35} + \frac{25}{35}}}}}$

${ \red \rightarrow{\large{ \sf{ \frac{ - 14 + 25}{35}}}}}$

${ \red \rightarrow{\large{ \sf{ \frac{11}{35}}}}}$
