Question

what should be added to (7/5+3/5+1/5) to get 7​

Answer 1

Answer:

$let \: the \: number \: which \: is \: to \: be \: added \: to \: get \: 7 \: be \: x$

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

$x + \frac{11}{5} = 7$

$x = 7 - \frac{11}{5}$

$x = \frac{35}{5} - \frac{11}{5}$

$x = \frac{24}{5}$
