1

Determine the value of an expression at
w = 2/5, x = 1/5, y = 8/5 & z = 9/5

\$ wx + yz + x + z \$

2

Now substitute "\$w,x,y,z\$" values in the expression

\$ (2/5)(1/5) + (8/5)(9/5) + 1/5 + 9/5 \$

3

After multplication we get

\$ 2/25 + 72/25 + 1/5 + 9/5 \$

4

Taking LCM as "25" we get

\$ (2 + 72 + 1\times5 + 9\times5)/25 \$

5

After multplication we get

\$ (2 + 72 + 5 + 45)/25 \$

6

After simplification we get, we get

\$ 124/25 \$

7

Answer

C = \$ 124/25 \$
