iii) $3\frac{1}{4}$

Answer 1

Step: Expressing mixed fractions as improper fractions.

To convert a mixed fraction to an improper fraction, we have to add the whole part with the fractional part.

$3\frac{1}{4}=3+\frac{1}{4}$

=$\frac{3\times 4+1}{4}$

[After taking LCM]

=$\frac{12+1}{4}=\frac{13}{4}$

$\therefore$ $3\frac{1}{4}$ as an improper fraction is $\frac{13}{4}$
