Question

Find the ratio of :
(i)300 meter to 9 km.
(ii)9 kg to 270 gram

Answer 1

Answer:

(i) = 1:30

(ii) = 100 : 3

Step-by-step explanation:

Given ;

(i) 300 m to 9 km

(io) 9 kg to 270 g

To find :

The ratio

Concept :

First make the km into m .......... (i)

And also make kg into g ............ (ii)

And then make them in the fraction and convert it to simplest form .

Solution :

(i)

1 km = 1000 m

So , 9 km = 9000 m

Ratio -:

$:\implies\sf{R=\dfrac{\cancel{300}m}{\cancel{9000}m}}$

$:\implies\sf{R=\dfrac{1}{30}}$

$:\implies\sf{R=1:30}$

(ii)

1 kg = 1000 g

So , 9 kg = 9000 g

Ratio -:

$:\implies\sf{R=\dfrac{\cancel{9000}g}{\cancel{270}g}}$

$:\implies\sf{R=\dfrac{100}{3}}$

$:\implies\sf{R=100:3}$

Answer 2

Answer:

(i) 1: 30 (ii) 100: 3

Step-by-step explanation:

(i) 1 km = 1000 m

So, 9 Km = 1000 m * 9

= 9000 m

Hence , The ratio of 300 m to 9 km is

= 300 m : 9 km

= 300 m : 9000 m

= 300 m / 9000 m

= 1 / 30

= 1: 30 (Ans . )

(ii) 1 kg = 1000 g

So, 9 kg = 1000 g * 9

= 9000 g

Hence , The ratio of 9 kg to 270 g:

= 9 kg : 270 g

= 9000 g : 270 g

= 100 : 3 ( Ans. )
