Question

find the ratio of 30min to 45min​

Answer 1

Answer:

the ratio of 30min to 45 min =30/45min

=2/3min or 2:3 min

Answer 2

The representation of ratio a to b is given as a: b

We have the definition of ratios that is

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

By using the above definition we find the required ratio after converting the numbers into the same units.

We are asked to find the ratio of 30 minutes to 45 minutes

Let us assume that the ratio of 30 minutes to 45 minutes as x

We know that the condition that the representation of ratio a to b  is given as a:b

By using the above condition we get

⇒x=30:45

We know that the definition of ratios that is

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

By using the above definition we get the required ratio as

⇒ x= $\frac{30}{45}$

⇒x=$\frac{2}{3}$

Now, again by using the definition of ratios, we get the required ratio as

⇒x=2:3

Therefore, we can conclude that the ratio of 30 minutes to 45 minutes is 2:3
