Find the difference by converting both mixed numbers to fractions with a common denominator.<br><br>
&bull; \(1\frac{1}{3} = \frac{4}{3}\) and \(1\frac{1}{4} = \frac{5}{4}\)<br>
&bull; LCM of 3 and 4 is 12.<br>
&bull; \(\frac{4}{3} = \frac{16}{12}\) and \(\frac{5}{4} = \frac{15}{12}\)<br>
&bull; \(\frac{16}{12} - \frac{15}{12} = \frac{1}{12}\)<br><br>
Mrs. Wong has \(\frac{1}{12}\) kg more flour than Dillie.<br>
Check: \(1\frac{1}{4} + \frac{1}{12} = 1\frac{3}{12} + \frac{1}{12} = 1\frac{4}{12} = 1\frac{1}{3}\). ✓
