Question

plz example.... it I am confuse​

Answer 1

Note: I am explaining the first question of the following picture as you are confused.

Step-by-step explanation:

We all know that 1kg is 1000g, right?

So, 25kg will mean 25 x 1000 which is 25000g.

Since the ratio written by the user has 25kg first, I am assuming that the question is 25kg : 20g.

Ratio is written as- 1st unit : 2nd unit.

So, the ratio will be 25000:20 (we don't add the unit in a ratio).

In both of the units, there is one zero in common which gets cancelled, resulting in 2500:2.

Since 2500 can be divided by 2, the ratio will become 1250:1.

Hope this helps...
