​

Answer 1

$\huge\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{...}}$

$\sf \implies\dfrac{x}{100} \times 34 = 1.7$

$\sf \implies 34x = 1.7 \times 100$

$\sf \implies 34x = 170$

$\sf \implies x = \dfrac{170}{34}$

$\sf \implies x = 5\%$

Answer 2

Answer:

⟹100x×34=1.7

\sf \implies 34x = 1.7 \times 100⟹34x=1.7×100

\sf \implies 34x = 170⟹34x=170

\sf \implies x = \dfrac{170}{34}⟹x=34170

\sf \implies x = 5\%⟹x=5%
