Question

2. Suppose 2 kg of wheat contains 7 x 10⁶crystals. How many wheat crystals are there in
(i) 4 kg of wheat?
(ii) 1.2 kg of wheat?​

Answer 1

Answer:

4 kg wheat 7x106x2 = 1484

1.2 kg wheat 7x106/ 2 = 371

1g = 37.1 g

so 1.2 g = 37.1+37.1 = 74.2

Answer 2

Answer:

2 kg contain crystal =7*10²

so for 4 kg

4 kg=4 *7*10⁶

=28*10⁶crystals

for 1.2kg

1.2*7*10⁶

8.4*10⁶ crystals
