Question

what should be subtracted from (5/14+3/7)to get 1/5?​

Answer 1

Answer:

5×14+3×7=1×5

=70+21=5

=19×5

=59

Answer 2

Let the required number be x

According to the question,the equation would be something like this:

$\sf{ \frac{5}{14} + \frac{3}{7} - x = \frac{1}{5} }$

Taking LCM on the left hand side,

$\implies \: \sf{ \frac{11 - 14x}{14} = \frac{1}{5} } \\ \\ \implies \: \sf{ \frac{ - 14x}{14} = \frac{1}{5} - \frac{11}{14} } \\ \\ \implies \: \sf{ - x = \frac{14 - 55}{70} } \\ \\ \implies \: \sf{x = \frac{41}{70} }$
