Answer 1

Fractions with same denominators are like fractions.

$\frac{9}{15}$, $\frac{4}{15}$ and <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{7}{15}$ are like fractions.

Fractions with different denominators are unlike fractions.

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{15}{11}$, <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{15}{4}$, <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{1}{2}$, <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{15}{7}$, <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{8}{9}$.
