Answer 1

Heya
______________________________

1kg = 10³ g

10kg 50g = 10⁴g + 50g = 10050g

And

4kg 690g = 4000g + 690g = 4690g

ACCORDING TO THE QUESTION

15 balls weight 1050g

=>

Number of balls in 1g = (15/10050)balls

Multiply both sides by 4690

=>

Number of balls in 4690g = (15×4690)/10050

=>

Number of balls in 4690g = 7 balls

=>

Number of balls in 4kg 690g is 7balls
