7	Answer	C = \$ 17/12 \$

Steps

Problem

Solution

Simplify

\$ 5/2 - 5/6 - 2/3 \times 3/8 \$

By using PEMDAS rule

\$ 5/2 - 5/6 - \cancel(2)^1/\cancel3^1 \times \cancel3^1/\cancel8^4 \$

After cancelation

\$ 5/2 - 5/6 -1/4 \$

Taking LCM as '\$12\$'

\$ (5 \times 6 - 5 \times 2 1 \times 3 )/12 \$

After Multiplication

\$ (30 -10 - 3)/12 \$

After simplification

\$ 17/12 \$

Answer

C = \$ 17/12 \$
