Answer

Problem

Determine the value of an expression when a = 8, b = 4, c = 2
\$ a/b + b/c + c/a \$

Step

Now substitute a,b,c values in expression

\$ \cancel8^2/\cancel4^1 + \cancel4^2/\cancel2^1 + \cancel2^1/\cancel8^4 \$

Step

After cancellation we get

\$ 2 + 2 + 1/4\$

Hint

Taking LCM as 4

Step

After simplification

\$ (8 + 8 + 1)/4 \$

Step

After adding we get

\$ 17/4\$
