would weigh 4.5 kilograms?

Answer 1

Solution!!

The weight of 25 precious stones is given. In these type of questions, we can simply apply unitary method and we'll get the answer.

25 precious stones weigh = 50 g

1 precious stone weigh = 50 g ÷ 25

1 precious stone weigh = 2 g

Now, let's convert the units. We know that,

1 kg = 1000 g

So,

4.5 kg = 4.5 × 1000 g

4.5 kg = 4500 g

Number of precious stones which weigh 4500 g = 4500 g ÷ 2 g

Number of stones which weigh 4500 g = 2250

Hence, 2250 precious stones would weigh 4.5 kg.
