Question

9. If a/5 = b/2, find the value of
a3-b3/b3​

Answer 1

Answer:

$\frac{117}{8}$

Step-by-step explanation:

Given in Question

$\frac{a}{5} =\frac{b}{2}$

We can write it as

$\frac{a}{b} =\frac{5}{2}$

Put the value of $a=5$ and $b=2$

$\frac{a3-b3}{b3} =$$\frac{5^{3}-2^{3} }{2^{3} }$

$\frac{125-8}{8}$

$\frac{117}{8}$
