$\huge\sf\purple{Steps}$

≫ So here we have to first find how much does it take tomake a single ribbon,that is,

»» $\sf \dfrac{195}{13}$

»» $\sf Length_{Per \ ribbon} = \red{15 cm}$

≫ Now, for 175 bookmarks we need,

➝ $\sf 175 \times 15$

➝ $\sf \green{Length = 2625 \ cm}$

Now we know that,

➠ 1 m = 100 cm

2625 cm will be,

➳ $\sf\dfrac{2625}{100}$

➳ $\sf\orange{26.25 \ m}$

$\rule{170}3$
