Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Solve: $\frac{3}{4}$ - <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1}{3}$

Answer 1

$\frac{3}{4}$ - <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1}{3}$

LCM of 3 and 4 = 12

$\frac{3}{4}$ - <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1}{3}$ = $\frac{3\times 3}{4\times 3}$ - <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1\times 4}{3\times 4}$

= $\frac{9}{12}$ - <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{4}{12}$

= $\frac{5}{12}$
