What should be added to

$( \frac{1}{4} + \frac{3}{8} )$ to get $\frac{ - 7}{25}$?

★Solution★

In order to find out the required number that should be added to

$( \frac{1}{4} + \frac{3}{8} )$ to get $\frac{ - 7}{25},$

we have to subtract $( \frac{1}{4} + \frac{3}{8} )$ from $\frac{ - 7}{25}.$

Now,

$\frac{1}{4} + \frac{3}{8}$ = $\frac{2 + 3}{ 8} = \frac{5}{8}$

So,

$\frac{ - 7}{25} - \frac{5}{8}$ = $\frac{ - 56 - 125}{200} = \frac{ - 181}{200}$

Therefore,

$\frac{ - 181}{200}$ should be added to $( \frac{1}{4} + \frac{3}{8} )$ in order to get $\frac{ - 7}{25} .$
