What number should be subtracted from \[\frac{3}{7}\] to get\[\frac{5}{4}?\]
Advertisements
उत्तर
\[\text{Let, x be subtracted .} \]
\[ \therefore \frac{3}{7} - x = \frac{5}{4}\]
\[ \Rightarrow x = \frac{3}{7} - \frac{5}{4}\]
\[ \Rightarrow x = \frac{12}{28} - \frac{35}{28}\]
\[ \Rightarrow x = \frac{12 - 35}{28} = \frac{- 23}{28}\]
