Answer 1

Step-by-step explanation:

$\frac{51}{45} \times \frac{21}{17} \times \frac{5}{7} \\ = 1 \frac{6}{45} \times 1 \frac{4}{17} \times \frac{5}{7} \\ = 1 \frac{2}{15} \times 1 \frac{4}{17} \times \frac{5}{7} \\ = \frac{17}{15} \times \frac{21}{17} \times \frac{5}{7} \\ = 1$

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

$\implies \dfrac{51}{45} * \dfrac{21}{17} * \dfrac{5}{7} \\ \text{Rearranging the numbers,} \\ \implies \dfrac{51}{17} * \dfrac{21}{7} * \dfrac{5}{45}$

We know that

• 51/17 = 3---(17*3=51),
• 21/7 = 3---(7*3=21) and
• 5/45 = 1/9---(5*9=45).

So,

$\\ \implies \dfrac{3*3}{9} \\ \implies \textbf{1}$
