Step-by-step explanation:

Answer 2

Answer:

a) the quantities are always in the same unit

Step - by - step explanation:

Ratio is a means to compare quantities.

You cannot compare quantities if they have different units.

For eg - compare or find the ratio of 1 km to 1 m

Here, we can see that the numerical value for both is 1.

But the units are different so they are not equal.

We can compare them only if we make the units same.

1 km = 1000 m

now we have 1000 m and 1 m

we can easily say that 1 km is greater than 1 m as 1000 m is greater than 1 m.

Therefore, it is really important to always make the quantities having same units.
