Question

if 3 is equals to b by 4 is equals to 7 then a + b + c by C is equals to​

Answer 1

Answer:

The value of \frac{a+b+c}{c} is 2.

It is given that

\frac{a}{3}=\frac{b}{4}=\frac{c}{7}

Using this we can say that,

\frac{a}{3}=\frac{c}{7}

\frac{a}{c}=\frac{3}{7} .... (1)

\frac{b}{4}=\frac{c}{7}

\frac{b}{c}=\frac{4}{7} .... (2)

\frac{a+b+c}{c}=\frac{a}{c}+\frac{b}{c}+\frac{c}{c}

Using (1) and (2) we get

\frac{a+b+c}{c}=\frac{3}{7}+\frac{4}{7}+1

\frac{a+b+c}{c}=\frac{3+4}{7}+1

\frac{a+b+c}{c}=\frac{7}{7}+1

\frac{a+b+c}{c}=1+1=2

Therefore the value of \frac{a+b+c}{c} is 2.
