Detailed Solution

Concept: In order to solve this issue, it is necessary to understand that 1 kg is equal to 1000 grammes and that the ratio a: b can also be written as

. The formula 1 kilogramme = 1000 grammes will be used to convert 7 kg to grammes, and then it will be expressed in the ratio form so that we may apply all of those operations to a: b, which we can apply to

. Now we need to discover the ratio of 7 kg to 700 grams.
First, it's important to understand that all formulas and operations that can be applied to

may also be applied to a: b.
Prior to simplifying the 7 kilogram to 700 g ratio, we must convert 7 kg to grams on the assumption that 1 kg equals 1000 grams, yielding 1 kg = 1000 grams.
When we multiply both sides by 7, we obtain 7 kg = 7000 grams.
Next, we'll represent it as a ratio, which gives us the result = 7000 grammes : 700 grams.
