$\rm \huge Solution :)$

$\rm length \: of \: ribbon \: bought \: by \: sarita = \frac{2}{5} \: metre \\ \rm length \: of \: ribbon \: bought \: by \: lalita = \frac{3}{4} \: metre \\ \\ \rm •°• \: length \: of \: ribbon \: bought \: by \:sarita \: and \: lalita \\ \rm = \frac{2}{5} \: metre \: + \: \frac{3}{4} \: metre \: = \: ( \frac{2}{5} + \frac{3}{4})metre \\ \rm = \frac{2} {5} \times \frac{4}{4} \: + \:\frac{3}{4} \times \frac{5}{5} = \frac{8}{20} \: + \: \frac{15}{20} \\ \rm = \frac{8 + 15}{20} \\ \rm = \frac{23}{20} \\ \rm hence \: the \: required \: length \: = \: \frac{23}{20} \: metre.$
