Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Simplify	\$ (-14/12) \div 14/18 \div 4/3 \$
2	By using the formula \$(1/a) \div (1/b) = (1/a) \times b\$	\$ (-\cancel14^1/\cancel12^2) \times \cancel18^3/\cancel14^1 \div 4/3 \$
3	After cancelation	\$ (-3/2) \div 4/3 \$
4	After simplification	\$ (-3/2) \times 3/4 \$
5	After multiplication	\$ -9/8 \$
6	Answer	D = \$ -9/8 \$

Steps

Problem

Solution

Simplify

\$ (-14/12) \div 14/18 \div 4/3 \$

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

\$ (-\cancel14^1/\cancel12^2) \times \cancel18^3/\cancel14^1 \div 4/3 \$

After cancelation

\$ (-3/2) \div 4/3 \$

After simplification

\$ (-3/2) \times 3/4 \$

After multiplication

\$ -9/8 \$

Answer

D = \$ -9/8 \$
