Question

If a:b:c is 5:3:4 then the ratio (a+b+c):c is equal

Answer 1

Answer:

(a+b+c)=5x+3x+4x.

=12x

the ratio is (a+b+c):c=12x:4x.

3:1.

Answer 2

Concept:

Ratio is the comparison between two or more number or mathematical quantities etc.

Given:

Given that, the ratio of a:b:c is given by 5:3:4.

Find:

We have to find the ratio of the term (a+b+c):c.

Solution:

Given that the initial ratio between a:b:c is 5:3:4

Let the a be equal to 5k, where k is the non zero constant.

b equal to 3k and c equal to 4k.

Then in this way the value of (a+b+c) = (5k+3k+4k) = (5+3+4)k = 12k

Then the ratio of the term (a+b+c):c is given by,

=  (a+b+c) : c

= 12k : 4k

= 12 : 4 (eliminating k)

= 3 : 1

Hence the ratio of (a+b+c):c is given by 3:1.
