Suppose 2 kg of sugar contains 9 x 10⁶ crystals. How many sugar crystals are there in (i) 5 kg of sugar? and (ii) 1.2 kg of sugar?

Solution: Let the required number of sugar crystals be x in 5 kg of sugar.

We have:

(i)

Weight of sugar	Number of sugar crystals
2	9 x 10⁶
5	X

Solution: Let the required number of sugar crystals be x in 5 kg of s

(ii) Let the number sugar crystals in 1.2 kg of sugar be y.

∴We have:

Weight of sugar	Number of sugar crystals
2	9 x 10⁶
1.2	y

Solution: Let the required number of sugar crystals be x in 5 kg of s
