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

Steps

Problem

Solution

Solve

\$ 2n + n/1 + n/2 = 1 \$

Taking LCM as '\$2\$'

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

After Addition

\$ (7n)/2 = 1/1 \$

By using cross multiplication

\$ 7n = 2 \$

Dividing on both sides by '\$7\$' of the equality

\$ \cancel(7)^1/ \cancel(7)^1 n = 2/7 \$

After cancelation

\$ n = 2/7 \$

Answer

C = \$ n = 2/7 \$
