Question

Find answers to the following. Write and indicate how you solved them.

(a) Is <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{9}{6}$ equal to <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{5}{9}$?

(b) Is <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{4}{5}$ equal to <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{16}{20}$?

Answer 1

Part (a)
Given fractions are $\frac{9}{6}$ and $\frac{5}{9}$
we have:
$9\times 9=81$ (Cross multiplication)
and $6\times 5=30$
Now, $9\times 9\ne 6\times 5$
Thus, $\frac{9}{6}\ne \frac{5}{9}$.

Part (b)

Given Fractions are $\frac{4}{5}$ and <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $\frac{16}{20}$
Now, we have
$4\times 20=80$ (Cross multiplication)
and $5\times 16=80$
Now, $4\times 20=5\times 16$
Thus, $\frac{4}{5}=\frac{16}{20}$
