Answer:The answer is option (a)

Step-by-step explanation: For this question, since all 3 terms have the same power, you compare the bases and ignore the powers. So you have 3/5 × 15/10 = x/y. That is 45/50 = x/y. Reducing to the lowest terms 9/10 = x/y. I hope that helped.

Answer:

(a)

Step-by-step explanation:

Since all ratios are raised to the power of 4, then

$\frac{x}{y}$

= $\frac{3(15)}{5(10)}$

= $\frac{45}{50}$ = $\frac{9}{10}$ → (a)

Anit [1.1K]

$\text{Answer : Number of \$45 shares} =120$

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$

Explanation:

Let Number of $45 shares be x

Let number of $ 25 shares be 3x-25

According to question,

$x+3x-5=475\\\\4x-5=475\\\\4x=475+5\\\\4x=480\\\\x=\frac{480}{4}\\\\x=120$

So,

$\text{Number of \$45 shares} =120$

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$
