Step-3

Title: Determine the value of an expressions

Grade: 6-b Lesson: S3-L9

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

Lesson Steps

Steps	Problem	Solution
1	Determine the value of an expression by substituting the value c = -3	\$ c/9 + 2/7 \$
2	Now substitute "c" value in the expression	\$ \cancel(-3)^1/\cancel9^3 + 2/7 \$
3	After cancellation we get	\$ -1/3 + 2/7 \$
4	Taking LCM as 21	\$ (-7 + 6)/21 \$
5	After simplification we get	\$ -1/21 \$
6	Answer	A = \$ - 1/21 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
c = -3

\$ c/9 + 2/7 \$

Now substitute "c" value in the expression

\$ \cancel(-3)^1/\cancel9^3 + 2/7 \$

After cancellation we get

\$ -1/3 + 2/7 \$

Taking LCM as 21

\$ (-7 + 6)/21 \$

After simplification we get

\$ -1/21 \$

Answer

A = \$ - 1/21 \$
