Question

Q.: Find the ratio of 10 km per hour to 30 km per hour?​

Answer 1

• As per the data given in the question, we have to find the ratio the 10km per hour into 30km per hour.
• The relationship between the two numbers is expressed in fractions having the same units of measurement is known as ratios.
• The ratio of $x$ to $y:$

        $=\frac{x}{y} or x:y$.

        The ratio of given quantity will be,

        $=\frac{10 km per hour }{30 km per hour}$

        $=\frac{1}{3} \\\\=1:3.$

        Hence, The ratio will be $1:3.$

Answer 2

From the given question the correct answer is:

the ratio of 10 km per hour to 30 km per hour is 1:3

Given:

10 km per hour to 30 km per hour

To find:

ratio of 10 km per hour to 30 km per hour

Solution:

given that,  we have to find the ratio the 10km per hour into 30km per hour.

The relationship between the two numbers is expressed in fractions having the same units of measurement is known as ratios.

The ratio of a to  b

So, a:b = $\frac{a}{b}$

as per the given data=$=\frac{10 km per hour}{30 km per hour}$

                                       $=\frac{10km/1hour}{30km/1 hour}$

                                         $=\frac{10km}{30km}$

                                           $=\frac{1}{3}$

so, we know that,

$=\frac{1}{3}$= 1:3

Hence , the ratio of 10 km per hour to 30 km per hour is 1:3
