There are two castings, one weighing 5 kg and the other 500 g. Compare the weights.

Concept:

Ratio:

• Ratio, in math, is a term that is used to compare two or more numbers.
• It is used to indicate how big or small a quantity is when compared to another.
• In a ratio, two quantities are compared using division.
• Here the dividend is called the 'antecedent' and the divisor is called the 'consequent'.

Calculation:

Given:

The weights of the two castings are 5 kg and 500 g

∵ 1 Kg = 1000 grams

∴ 5 Kg = 5000 grams

Comparing the weights of the castings:

⇒ 5000 : 500

⇒ 10 : 1
