Title: Solve the equation

Grade: 7-b Lesson: S2-L4

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

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ n/4 + (2n)/3 + n/2 = 1 \$
2	Taking LCM as '\$12\$'	\$ (3n + 8n + 6n)/12 = 1 \$
3	After Addition	\$ (17n)/12 = 1/1 \$
4	By using cross multiplication	\$ 17n = 12 \$
5	Dividing on both sides by '\$17\$' of the equality	\$ \cancel(17)^1/ \cancel(17)^1 n = 12/17 \$
6	After cancelation	\$ n = 12/17 \$
7	Answer	B = \$ n = 12/17 \$

Steps

Problem

Solution

Solve

\$ n/4 + (2n)/3 + n/2 = 1 \$

Taking LCM as '\$12\$'

\$ (3n + 8n + 6n)/12 = 1 \$

After Addition

\$ (17n)/12 = 1/1 \$

By using cross multiplication

\$ 17n = 12 \$

Dividing on both sides by '\$17\$' of the equality

\$ \cancel(17)^1/ \cancel(17)^1 n = 12/17 \$

After cancelation

\$ n = 12/17 \$

Answer

B = \$ n = 12/17 \$
