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 d = 4	\$ (4d)/64 + 9/4 \$
2	Now substitute "d" value in the expression	\$ (4(4))/64 + 9/4 \$
3	After simplification we get	\$ \cancel16^1/\cancel64^4 + 9/4 \$
4	After cancellation we get	\$ 1/4 + 9/4 \$
5	Taking LCM as 4	\$ (1 + 9)/4 \$
6	After simplification we get	\$ \cancel10^5/\cancel4^2 \$
7	After cancellation we get	\$ 5/2 \$
8	Answer	B = \$ 5/2 \$

Steps

Problem

Solution

Determine the value of an expression by substituting the value
d = 4

\$ (4d)/64 + 9/4 \$

Now substitute "d" value in the expression

\$ (4(4))/64 + 9/4 \$

After simplification we get

\$ \cancel16^1/\cancel64^4 + 9/4 \$

After cancellation we get

\$ 1/4 + 9/4 \$

Taking LCM as 4

\$ (1 + 9)/4 \$

After simplification we get

\$ \cancel10^5/\cancel4^2 \$

After cancellation we get

\$ 5/2 \$

Answer

B = \$ 5/2 \$
