7	Answer	D = \$ - 27/70 \$

Steps

Problem

Solution

Simplify

\$ (-3) \div (-3 1/3) \div (-7/3) \$

After simplification

\$ (-3) \div (-10/3) \div (-7/3) \$

By using the formula \$(1/a) \div (1/b) = (1/a) \times b\$

\$ (-3) \times (-3/10) \div (-7/3) \$

After cancelation

\$ 9/10 \div (-7/3) \$

After simplification

\$ (9/10) \times (-3/7) \$

After multiplication

\$ -27/70 \$

Answer

D = \$ - 27/70 \$
