Question

Compare 4 : 5 and 7 : 9.

answer - (4:5) >(7:9)


​

Answer 1

Answer:

yes

Step-by-step explanation:

your answer is correct 4:5 > 7:9 is correct

Answer 2

Answer:

4:5 means that there are 5 parts of a whole and we have 4 parts.

But 7:9 means there are 9 parts of a whole and we have 7 of them.

If we divide a whole into 5 parts and grab up 4 parts then 1/5 is left.

In the same way,

If we divide a whole into 9 parts and grab up 7 parts then 2/9 is left.

So logically,

4:5 > 7:9

______________________________________

Another way to do it is mathematically,

In this method we just need to make the denominators of the fractions equal.

We can do it by,

Step:1 - Take LCM of the denominators

In this case we take LCM of 5 and 9

So the LCM is 45.

Step:2- Make the denominators equal by multiplying a number in the denominator to make it equal to the LCM

In this case

$\frac{4 \times 9}{5 \times 9}$

$= > \frac{36}{45}$

and

$\frac{7 \times 5}{9 \times 5}$

$= > \frac{35}{45}$

On Comparing we get 4:5 > 7:9
