What is the solution for the expression a/b + c if a/b = 4 and b/c = 2?

• A. 8/3
• B. 6/3
• C. 10/3
• D. 4/3

Answer: (A)

To solve the expression \( a/b + c \) given the conditions \( a/b = 4 \) and \( b/c = 2 \), we can first express \( a \) and \( c \) in terms of \( b \). Starting with the information that \( a/b = 4 \), we can infer that \( a = 4b \). Next, from the equation \( b/c = 2 \), we can rearrange this to express \( c \) in terms of \( b \): \[ c = b/2. \] Now, substituting these expressions into the original equation \( a/b + c \): \[ a/b + c = 4 + (b/2). \] To add these together, we need a common denominator. The term \( 4 \) can be rewritten as \( 8/2 \): \[ 4 = \frac{8}{2}. \] Combining these gives: \[ \frac{8}{2} + \frac{b}{2} = \frac{8 + b}{2}. \] Now, we need to determine the value of \( b \). From \( b/c = 2 \), we

To solve the expression ( a/b + c ) given the conditions ( a/b = 4 ) and ( b/c = 2 ), we can first express ( a ) and ( c ) in terms of ( b ).

Starting with the information that ( a/b = 4 ), we can infer that ( a = 4b ).

Next, from the equation ( b/c = 2 ), we can rearrange this to express ( c ) in terms of ( b ):

[

c = b/2.

Now, substituting these expressions into the original equation ( a/b + c ):

[

a/b + c = 4 + (b/2).

]

To add these together, we need a common denominator. The term ( 4 ) can be rewritten as ( 8/2 ):

[

4 = \frac{8}{2}.

]

Combining these gives:

[

\frac{8}{2} + \frac{b}{2} = \frac{8 + b}{2}.

Now, we need to determine the value of ( b ). From ( b/c = 2 ), we
