Question

the compound ratio of 5:6, 3:2 and 4:5​

Answer 1

Answer:

7:10

Step-by-step explanation:

Given 5:6 :: 7:10 :: 6:5

We know that compound ratio is calculated as

a:b :: c:d :: e:f

(axcxe):(bxdxf)

=> (5x7x6):(6x10x5)

=> (210):(300)

= 7:10

Answer 2

Answer:

Compound ratio of 5:6, 3:2 and 4:5​ is $1:1$.

Step-by-step explanation:

Ratio involving two or more quantities is called compound ratio.

When two or more ratios are multiplied ,the ratio new thus obtained is called compound ratio.

For ratios m:n and p:q; the compound ratio is (m×p):(n×q).

For example:

The compound ratio of the two ratios 2:3 and 4:5 is the ratio 2×4:3×5=8:15,

Proportionality allows us to relate two or more quantities. In the case of compound proportionality, we are relating three quantities at the same time. Compound proportionality is represented as $y\alpha xz$. If we use the constant k, we can form the equation $y = kxz.$

A Compound ratio with two equal ratios is called a Duplicate Ratio. A Compound ratio with three equal ratios is called a Triplicate Ratio.

Given: Ratios $5:6, 3:2, 4:5$

For ratios m : n, p : q and r : s

the compound ratio = (m × p × r) : (n × q × s)

So, Compound ratio:

$5\times3\times4 : 6\times2\times5\\=60:60\\=1:1$
