30/45:25/54

0.6667:0.4629

1.44

Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of ratio will be used to solve this question.An ordered pair of numbers $a$ and $b$, represented as $\frac{a}{b}$, is a ratio if $b$ is not equal to $0$.

Given:

The ratio of $m:n$ is $5:9$ and the ratio whose value will be get is $(6m:5n):(5n:6n)$.

To Find:

The value of $(6m:5n):(5n:6n)$ will be evaluated by using the given values.

Solution:

The value of $m$ is $5x$ and the value of $n$ is $9x$ .

The first ratio is $(6m:5n)$ .

Put the value in this ratio.

$(6m:5n)=6 \times 5x : 5 \times 9x=\frac{6}{9}$.

The second ratio is $(5n:6n)$.

Put the value in this ratio also.

$(5n:6n)= 5 \times 9x : 6 \times 9x=\frac{5}{6}$

Now the new ratio is $(6:9):(5:6)$

$(6:9):(5:6)=\frac{6}{9} \times \frac{6}{5} =\frac{4}{5}$

The final ratio is $4:5$ .
