The ratio of a to b is 3 to 1, and the ratio of b to c is 1 to 5. What is the value of 2a+3b/ 4b+3c?
Nostrana [21]

Answer:

B

Step-by-step explanation:

Expressing the ratios as fractions, that is

\frac{a}{b} = \frac{3}{1} ( cross- multiply )

a = 3b

\frac{b}{c} = \frac{1}{5} ( cross- multiply )

c = 5b

------------------------------------------

Given

\frac{2a+3b}{4b+3c} , substitute values from above for a and c

= \frac{2(3b)+3b}{4b+3(5b)}

= \frac{6b+3b}{4b+15b}

= \frac{9b}{19b} ← cancel b on numerator/ denominator

= \frac{9}{19} → B
