(3) $\frac{27}{64}$

(4) $\frac{28}{105}$

Answer 1

Part $\left(1\right)$

$\frac{18}{26}$

Divide by a common factor $2$ and we get,

$\frac{9}{13}$

Part $\left(2\right)$

$\frac{56}{91}$

Divide by a common factor 7 and we get,

$\frac{8}{13}$

Part $\left(3\right)$

$\frac{27}{64}$

No common factor.

Part $\left(4\right)$

$\frac{28}{105}$

Divide a common factor $7$, we get

$\frac{4}{15}$

Hence, this is the answer.
