Question

Suppose 2 kg of sugar contains 9 x 106 crystals. How many sugar crystals are there in 5 kg of sugar?

​

Answer 1

Step-by-step explanation:

2 kg sugar contains 9×10^6 crystals

Therefore 1 kg sugar contains 9×10^6/2 crystals

9×10^6/2 = 4.5 × 10^6 crystals

So, crystals in 5kg sugar =

4.5 × 10^6 × 5=22.5 × 10^6 crystals
