Question

2.25 billion - 400 million?

Answer 1

Hey mate!! Here's your answer.
______________________________

1 billion = 1,000,000,000

Hence,
2.25 billion = 2.25 × 1,000,000,000
= 2,250,000,000

1 million = 1,000,000

Hence,
400 million = 400 × 1,000,000
= 400,000,000

Now,
2.25 billion - 400 million
= 2,250,000,000 - 400,000,000
= 1,850,000,000
= 1 billion 850 million $\mathcal{\red{Ans}}$
